IoT 101

What is IoT 101? The term IoT was coined by Kevin Ashton in 1999. At that time, most of the data fed to computers was generated by humans; he proposed that the best way would be for computers to take data directly, without any intervention from humans. And so he proposed things such as RFID and sensors, which gather data, should be connected to the network, and feed directly to the computer. Today IoT (also called the internet of everything and sometimes, the fog network) refers to a wide range of things such as sensors, actuators, and smartphones connected to …

Control Devices using Cloudchip

We live in an exciting time where more and more everyday items “things” are becoming smart! “Things” have sensors and can communicate to other “things” and can provide control to more “things”. The Internet of Things, IoT, is upon us in a huge way and people are rapidly inventing new gadgets that enhance our lives. The price of microcontrollers with the ability to talk over a network keeps dropping and developers can now tinker and build things inexpensively. Software Tools: 1.Arduino IDE 2.Cloudchip IoT Platform Hardware Tools: 1. NodeMcu 2. 4 Channel Relay Module 3. Bulbs Circuit:   Step1: Create …

IoT business models

As the penetration of the IoT continues in various industry verticals, we will see new business models evolve and new and creative ways of generating value for the end customers and therefore generating revenue. Before we look at possible emerging business models, it’s important to take a deeper look at how these technologies are being used today. We can divide the use of IoT technologies into the following broad categories: Smart monitoring of the existing product or service install base: The products and services that businesses sell today have monitoring, alerting, and reporting solutions. However, these are siloed and not …

IoT using Raspberry Pi

Introduction DHT11 sensor measures and provides humidity and temperature values serially over a single wire. It can measure the relative humidity in percentage (20 to 90% RH) and temperature in degree Celsius in the range of 0 to 50°C. It has 4 pins; one of which is used for data communication in serial form. Pulses of different TON and TOFF are decoded as logic 1 or logic 0 or start pulse or end of a frame. Interfacing diagram DHT11 Interfacing with Raspberry Pi 3 Example Here, we are going to interface the DHT11 sensor with Raspberry Pi 3 and display …

Sydney Harbour Bridge

              Sydney Harbour Bridge, Opened in March 1932, the iconic bridge is subjected to enormous amounts of traffic, and has traditionally been monitored by inspectors. The entryway from the north into the Sydney is the Sydney Bridge, it was built with great engineering standards but it still needs to be monitored and looked back. Over the years there has been an increase in vehicles and volume of the load carried by the trucks, the engineers are trying to understand how the bridge responds to the different loading and making sure that bridge will be able to accommodate those changes to …

The challenges in providing IoT security

More and more IoT devices are being deployed every day, making IoT systems more complex than ever. This leads to increased difficulty level in securing IoT systems. In the upcoming subsections, we will speak about the most common problems that are being faced today. Security in endpoint devices – constrained devices Most of our endpoint devices (constrained) that constitute the sensors, actuators, and controllers don’t have enough memory or processing power, and run on low and limited power. Due to these reasons, traditional security approaches cannot be applied to these constrained devices because they use heavy encryption and decryption algorithms …

MQTT Clients and Servers

Any device that has a TCP/IP stack and is capable of using an MQTT library can become an MQTT client, that is, a publisher, a subscriber or both a publisher and a subscriber. The MQTT library makes it possible for the device to talk MQTT on top of TCP/IP and to interact with specific types of MQTT servers. For example, any of the following can become an MQTT client: an Arduino board, a Raspberry Pi 3/4 board, an Intel Joule board, an android, iPad, a laptop running Windows, a server running Linux, a Macbook running macOS, and Android tablet, among …

Smart Agriculture Monitoring System

Project description  Since we know the benefits of proper soil moisture and its quality, air quality and irrigation, in the growth of crops, such parameters cannot be ignored. We, therefore, have come up with a new idea of crop monitoring and smart farming using IoT. We believe that our concept will be a benchmark in the agribusiness due to its reliability and remote monitoring. Our idea tries to digitize farming and agricultural activities so that the farmers can check on the requirements of the crops and accurately predict their growth. This concept will surely accelerate their business to reach new …
