The capabilities of IOT with the wearable devices like internet connectivity, a device to device communications, lightweight apps, data filtering, local and cloud analytics, etc.., are bringing many opportunities to develop more meaningful solutions for consumers. Here, I would like to talk about few of them.

paasmer_Wearables

The wearable devices with the technological innovation of IOT are widely successful in providing the fitness and healthcare related solutions. We have a lot of scope for environmental monitoring also, but the challenge is cost and power. A very few are successful in low cost and low power sensors in wearable devices used for environmental monitoring. These environmental devices can collect data on Air, Light, and Sound. With continuous innovations in sensors, we can expect that the manufacturing and operation cost of these devices will become more affordable and capable of sensing multiple environmental data. The wearable nature of the device gives constant mobility to the device. This opens up an opportunity to crowdsource the more accurate and real-time environmental data with location details. The data collected by the device can be from the sensors embedded in it and from other sensors in reachable distance based on the supported protocols and standards.

Having more accurate and crowdsourced real-time environmental data in the cloud combined with another cloud accessible real-time and forecasted environmental data from static stations set up by governments and institutes brings tremendous opportunities for IOT device manufacturers and solution providers to build innovative, value added, cost effective consumer devices and solutions.

In health care, the environmental data can be used for the clinical diagnosis and treatment of many human pathologies which are influenced or triggered by environmental stimuli. By analyzing the consumers’ health data like health history, medical records and any other health-related data with the environmental and location data, we can develop customized healthcare solutions to help consumers with health advisories and warnings. It can also be used to provide B2B solutions like connecting consumers with doctors for consultation, Pharmacy to order suggested list of things to order, etc.,

The consumer specific health data and location specific real-time and forecasted environmental data can also be used to provide travel advisories and b2b solutions with a list of things to carry based on the mode of transport and travel locations, and option to buy the recommended list of things online. So, with the capabilities of IOT, we still have lot of opportunities that can be explored with the wearable devices in healthcare, travel, city management, traffic management, waste management, disaster management, etc.,

Transforming Hydroponics and Aquaponics farming Using Internet of Things

ManagementTeamMouli1

Kavitha Gopalan

With the growth in urban population, the need for more space seems perpetual. Traditional farming techniques are known for the need of large lands and the enormous amount of water. So the need for revolutionary farming techniques which occupies lesser space, consume lesser water and can give larger produce have led to the popularity of farming methods like hydroponics and aquaponics.

Hydroponic farming is a system of growing plants without soil using nutrient-laden solution to deliver nourishment directly to the roots of the plants. In hydroponic farming, the idea is to create a controlled environment for the plants with the right level of temperature, moisture, CO2, pH, water level and nutrients and supplying this solution directly to the plant’s roots. This method of creating an optimal environment for plants helps to increase the productivity by 3 folds. It also has other benefits like the re-use of the nutrient solution, reduces the amount of water used for farming by recycling, reduced fertilizer usage and requires lesser space.

Aquaponics is a system which uses aquaculture with hydroponics. In an aquaponics system, water from an aquaculture system is fed to a hydroponics system where the by-products are broken down by nitrifying bacteria initially into nitrites and subsequently into nitrates, which are utilized by the plants as nutrients, and the water is then recirculated back to the aquaculture system.

While these new techniques promise great results, it has certain inherent challenges which inhibit its widespread adoption.

The biggest hurdle for its adoption is the maintenance of the system. It could be time-consuming and be challenging to understand and constantly monitor the hydroponic or aquaponic systems.

Setting up these systems could be a mammoth task, the number of sensors to be installed, the triggers and the parameter configuring could be time-consuming.

It also requires constant monitoring of the sensors and the system. A hydroponic farm must be regularly attended to by a farmer, to know if there is any blockage in the drainage system, to understand if any system failure/power failure if the pump is on/off. If they must set-up multiple farms then scalability becomes an issue.

IOT will be a key problem solver for hydroponics and aquaponics systems with its ability to connect various sensors in the field to cloud and allowing it to be monitored and controlled from anywhere.

The Union of Internet of Things and hydroponic farming will be the future of demystifying the hydroponic farming and making it easier for adoption.

The internet of things will bring in features like automation, remote monitoring and control and build intelligence into the hydroponic farming system. This helps to prevent the need for the human presence in the farm every time and allows efficient monitoring and control of the farm from a remote location.

Sensors mounted in the farm could be used for monitoring CO2, air current, lighting, fertilizer flow, and the pH of the soil. The readings from these sensors are then analyzed in cloud systems. These readings are monitored continuously and tuned if there is any change in environment. Immediate alerts of the status and action will result in increased yield.

Basic concepts in a Blockchain transaction

ManagementTeamMouli1

Chandramouli Srinivasan

In this blog, Demir talks about the basic terms used in Blockchain like Hashing, Decentralization, Digital Signature, Share Crypto currency, Minors (Agents), Blockchain (The Ledger).

Using Blockchain technology means

  1. All transaction is made over the Internet using P2P communication, thus removing the need for a central authority.
  2. Users can perform anonymous transactions by utilizing asynchronous cryptography and they are identified only by their private key/public key combination.
  3. You have implemented a validated global ledger of all transactions that has been safely copied to every peer in the network.

These decentralized technology fundamentals can be leveraged by any centralized technology currently being used like IoT, Financial systems, insurance systems etc. The increase in computing power requirement for Blockchain is a potential issue for Blockchain implementations. However, there are many types of researchers underway that could change the way a commercial and viable implementation of Blockchain occurs.

The Industrial Internet of Things can help the manufacturing industries to transform to a smart industry. It enables them to collect data on machines, manufacturing process, the products produced and the quality of the products from the systems like mechatronics, embedded systems, and sensor hardware network. IIOT offers analytical applications to extract information from the raw data collected from various systems. The information helps the industries to improve the efficiency of the manufacturing process that will result in improve their productivity with optimized cost and improved quality, implement automation and predictive maintenance to avoid breakdowns.

IIOT_Manufacturing

Challenges with mix of legacy and modern systems

The challenges and complexities of industries in implementing IIOT applications are various kinds of machines in the industry both legacy and modern. Most of the legacy machines have older sensors, controllers and proprietary systems, whereas the modern manufacturing equipment offers a wide selection of connectivity options, a whole range of data feeds and integrates data into modern data analytics software. The industry is working on to build and implement standard protocols, compatible interfaces and architectures to achieve full interoperability. But bringing old machines into IIOT is continue to be challenging as they require retrofitting of sensors, connectivity and simple compute endpoints to generate any kind of meaningful data at all.

Edge devices can solve the problem

The Edge or Gateway IIOT device which can act as a bridge between the data generating endpoints and IIOT cloud applications can solve the problem of connecting older sensors, controllers and proprietary system by custom implementations.The different kinds of capabilities can be added in the Edge devices to access different kinds of machines and sensors both legacy and modern.

The Internet of Things is set to disrupt the way we live and work, but for now, let’s focus on the “live” portion of that statement. Smart homes filled with connected products are loaded with possibilities to make our lives easier, more convenient, and more comfortable.

Imagine that you’re driving home on a hot summer day. But rather than turning the air conditioner on when you get home and wait for your house to cool, you simply use your smartphone when you leave your office to tell your smart thermostat to lower the temperature.

Or imagine that you’re cooking dinner, and you ask the voice assistant to read you today’s biggest news stories so that you can focus on making your kid’s favorite lasagne. There is no shortage of possibilities for smart home IoT devices, and home automation seems to be the wave of the future.

Experts estimate that the number of smart home devices shipped will grow from 83 million in 2015 to 193 million in 2020. This includes all smart appliances (washers, dryers, refrigerators, etc.), smart home safety and security systems (sensors, monitors, cameras, and alarm systems), and smart home energy equipment, like smart thermostats and smart lighting.

There are many benefits of home/building Automation which are listed below.

  • Security: Motion sensors
  • Efficiency: Automatic switch off when not in use.
  • Convenience: Control everything from your fingertips.
  • Savings: You save money with an efficient Home automation system.

The first and most obvious benefit to smart homes is a convenience, as more connected devices can handle more operations (lighting, temperature, etc.) and free up the resident to perform other tasks.

As with all shifts in technology, changes will happen in the ways we live and do business. With the actions being taken for more energy efficiency in construction and managing of buildings there is a big potential through Internet of Things. HVAC systems that can make their own intelligent decisions based on presence, weather and lots of other indicators have a great potential to cut energy use and cost.

We are also certain that new business models will emerge. HVAC systems using IoT will be able to predict situations from collected data and have automated alarms for service and maintenance that can facilitate new services.

Paasmer:

Mobodexter’s PAASMER provided the complete set of components to build this solution from End to End satisfying all the needs of the client in the shortest possible time frame.

Here we explain how PAASMER has been used to connect a traditional HVAC system using a custom built IR blaster to the Paasmer IoT platform and how to control the same remotely.

Paasmer_HVAC

The solution has 4 modules, the Hardware, the Misty OS, the Paasmer IoT Platform and the App. We shall look at each of them below.

Gateway Hardware:
The Gateway Hardware consists of Network MCU boards with an IR Receiver and an IR transmitter connected to it. The Firmware that runs on the Network MCU is responsible for connecting to the Paasmer IoT Platform and ability to send and receive data from the Paasmer IoT platform.

It is also responsible for decoding the correct pattern to be sent via the IR transmitter and recording the correct pattern from the IR receiver.

Misty OS:

Misty OS is designed to be flexible, modular and gateway platform agnostic. The core functionality of the OS, Connectivity, H/W interface and middleware component are built into Misty OS. The gateway has interfaces for IR Transmitter and an IR receiver

It operates in two modes, Learning, and Transmits.

In Learning mode, the Hardware learns all the new IR codes that are needed for a particular device and stores the data on the Paasmer IoT Platform specific to the user. The learning mode can be enabled from the App and has options to choose the device type and device subtype. Once all the buttons of the remote have been learned it is ready to work.

In Transmit mode, messages are received from the App via the Paasmer IoT platform inform the Hardware to blast out the appropriate IR signature for the button pressed in the App. This IR signal is blasted across and very wide range using duplicate IR transmitters to cover an almost 360-degree range to control the HVAC system.

Paasmer IoT Platform:

Paasmer is a one stop shop for connecting all your devices to the internet and read data from them as well as control them. The Paasmer IoT Platform hosts the message broker, the necessary business logic, data store and all the necessary interconnections between them. It provides a platform onto which all Gateway HW devices, mobile phones, websites can be interconnected.

App:

The App connects to the Paasmer IoT Platform and based on the user login details and displays the data of the devices that are available for control. The user can select the appropriate device and control the device using the buttons on his screen. These button clicks are translated to the respective messages which are published by the Paasmer IoT Platform.

Paasmer_HVAC_1

In the current scenario a user wants to switch off the HVAC, so he selects the HVAC and then switches it off. These switches off messages are published to the broker on a particular topic. The Gateway Hardware is subscribed to this particular topic and hence receives the message.

The Gateway Hardware then decodes the message and immediately blasts the respective IR signature to turn off the AC.

Demystifying the Blockchain Technology

ManagementTeamMouli1

Chandramouli Srinivasan

Blockchain promises to produce a shift in the current computing paradigm because it has the potential to become the infrastructure catalyst for the creation of decentralized applications. The Blockchain is being seen as the next-step evolution from distributed computing architectural constructs, to a global database of data and interfaces, integrating all kinds of machines and sources of data.

Four underlying concepts in Blockchain are:

  • Blockchain.
  • Decentralized databases applications consensus.
  • Smart contracts.
  • Proof of Stake(PoS).

1.Blockchain

As we all know blockchain technology started with the bitcoin. Bitcoin is a peer-to-peer electronic payments system, also known as a cryptocurrency, that allows people to make instant, anonymous transactions online.

The unique characteristic of bitcoin is that it records every single transaction made on its network in a public record. This is known as the “blockchain”. A new blockchain is created every ten minutes. That blockchain is afterward shared throughout the network. The chain is constantly growing because each completed “blocks” is added to the public ledger. There are an infinite number of blocks on the blockchain because as soon as one block gets completed, another is automatically generated.

2. Decentralized Databases Applications Consensus

Blockchain’s potential for the development of decentralized database applications consensus is based on the unique characteristics of the technology, as outlined previously.

A decentralized scheme, on which the bitcoin protocol is based, transfers authority and trust to a decentralized virtual network and enables its nodes to continuously and sequentially record transactions on a public “block” creating a unique “chain”: this is the inception and keywords genesis for blockchain.

3. Smart contracts

A scaled blockchain is something that starts proving a new global (somehow still science fiction) ecosystem. For this, the smart contracts are the building blocks for decentralized applications.

Smart contracts are contracts whose terms are recorded in a computer language instead of legal language. Smart contracts can be automatically executed by a computing system, such as a suitably distributed ledger system.

4. Proof of stake

Proof of stake (PoS) is a method by which a cryptocurrency blockchain network aims to achieve distributed consensus. While the proof of work (PoS) method asks users to repeatedly run hashing algorithms or other client puzzles to validate electronic transactions, proof-of-stake asks users to prove ownership of a certain amount of currency (their “stake” in the currency). Peercoin was the first cryptocurrency to launch using proof-of-Stake. With Proof of stake, the probability of mining a block depends on the work done by the miner (e.g. CPU/GPU cycles spent checking hashes).
