The IoT or Internet of Things is a technology that connects a network of devices embedded with various sensors, software, network, connectivity, and electronics to collect and exchange data.
The goal behind having the Internet of Things is to have devices self-report in real-time. Thus bringing important information to the surface faster than a system that relies on human intervention.
Various projects gained popularity very quickly on the IoT recently. So, let’s look at the Top projects on IoT for CSE students. These projects are very useful in this time as they really make the human effort minimum.
Let’s look at a few characteristics of IoT before we begin. It helps make devices smarter by connecting everyday electronic devices to the internet. They help with supply chain management by making it easier to track import/export chains and payments. Lastly, it helps industries read and understand data efficiently.
10 Best Projects on IoT for CSE
IoT based Weather Monitoring system:
This system deals with monitoring the weather conditions of a particular place/city. It tracks and gives constant updates on climate changes, humidity, temperature, moisture, wind speed, Ultraviolet radiation, light intensity, and carbon monoxide levels in the air using multiple sensors.
These sensors send data to the web page and are stored as graphical statistics. The application is also designed to send notifications to the application and effectively alert and warn authorities or people of sudden and drastic climate changes.
The application can tell you on a particular day or time, how the weather will be like and also suggest if you should be carrying your umbrella or jacket along with you for the day. The sensors used are DHT sensor, MQ-135 gas sensor, light, rain, pollution, and BMP-180 or air pressure sensor.
Automated Street Lighting using IoT:
The main aim of the automated street lighting system using the IoT is to conserve energy and electricity, avoid any wastage and reduce manpower. This system makes the human effort of physically putting ON or OFF the street lights every day according to the time of the day.
This smart street light system incorporates a cluster of street light lamps connected and then provides data to the local connector. The connector manages and transfers the data to a local server and presents it on the dashboard.
The IoT system uses a transistor to turn ON the street lights at night and turn them OFF in the daytime. The sensor used is an LDR (Light-dependent resistor).
The Biometric system can now be found in every office or workplace. It is used to track and monitor attendance and authorize the person before entry into the organization.
The system uses a microcontroller based circuit with a fingerprint sensor, push button, power supply, and wifi modem to interact and communicate with the internet.
Initially, an employee should register the fingerprint on the system. After successful registration, the fingerprint is stored in the system corresponding to the particular employee. The details are displayed on the LCD screen.
Next time the employee scans the fingerprint, the system transfer data online to IoT Gecko using API codes. The data can be remotely monitored over the IoT. Almost every big or small businesses use the Biometric system to update the login details for employees.
Home automation system using IoT:
The IoT system can be used to automate and control the home appliances like Television, Air conditioners, lights, water management, etc. The devices are integrated over a common network established by a gateway and connected in a mesh network.
They are connected to a central hub and then can be controlled using a mobile application. The sensors collect the data for the IoT to process and the identification and connection to the device are acquired using an IP address. Actuators allow the device to then take action based on the data from the sensors. We can operate so many home appliances using just one application and a click of a button.
This is not going to be the average home mirror that you use every day. The Smart Mirror will be able to display time, weather, temperature, news, and calendar. It will be able to switch on the lights on the mirror using a motion sensor when somebody comes in front of it.
It can even click pictures using an in-built camera. It can play your favourite music or even display an on-demand workout session for you. It can browse the internet and also connect or make a phone call.
It uses a Raspberry Pi processor board along with IoT circuits and a Wifi module. This helps the mirror receive data over the IoT platform. IoTGecko is used to connect the system to the internet and also get a newsfeed.
Smart Door system:
The smart door can control the entry and exit from the house’s main door. They can automatically open or close when you pass by once your credentials are updated.
It can also be controlled remotely using an app. You could unlock the door for a friend and are also notified when they leave through the app. You can restrict access to a stranger who is visiting without any authentication.
Smart locks leverage IoT enabled sensors. You can also distribute virtual keys to visitors to have access to the door. You can remotely control access to the door and the entry time and exit time for a particular person.
The smart Irrigation system has a moisture sensor that checks and updates the moisture content in the soil. When the soil moisture content drops below a certain value, the system triggers the water supply Once the moisture levels are met the system then turns off the motor and water supply.
This reduces the manpower of manually checking and watering plants, especially when there are many plants in a garden or a field. Water scheduling also can be planned during the day.
A particular time can be set to water the plants. You can enjoy your time with the plants without the hassle of watering each one of them personally.
IoT based Smart Arm:
This project includes the creation of a robotic arm that is used to do many things, like pick up and move objects. The robotic arm can be moved using specific commands. The end effect of the robotic arm can be changed for it to help with numerous tasks like, draw, print images or 3D images or even build a production line.
The process of controlling the robotic arm is through an open-source web application. The Raspberry Pi board is used for the direction and control of the robotic arm and the webserver system. The robotic arm is a very helpful feature to have in the production line of a factory. The manpower used is reduced to a great extent.
Smart wallet / Money Transfer:
This project aims at the complete digitisation of money transfer online through apps on your smartwatch. Apple Pay, Google Pay, PayPal etc can be used to make the transactions. The purpose of the smart wallet through your wristwatch is to provide an easy, convenient and reliable platform for money transactions. It is compact, wearable and rechargeable.
User authentication is used for security and validation before any transaction. This reduces the hassle of online money transactions through a certain wallet or bank card.
You can easily step into any store, make a purchase and pay hassle-free using the smartwatch by just swiping across the machine. After every transaction, the balance is updated immediately.
132 million people around the world use the wheelchair. The Smart Wheelchair comes with built-in sensors present on the seats that collect data every second, providing valuable insights on the patient. It gathers data such as posture and fall detection.
The smart wheelchair is multi-functioned. It can be used as a panic alarm if the patient is in distress. It has a LED light that can be used at night. The Smart wheelchair can also automatically identify obstacles in the path. Some of the equipment used is a Motor driver, Bluetooth module, Ultrasonic sensor, DC motor, LED, Push button to name a few.
It is estimated that the growth of IoT projects is going to be fast and furious. By 2025, it is estimated that there will be a whopping 21 billion IoT devices. More and more cities will become “Smart” cities. Artificial Intelligence will continue to grow and become more accessible.
Cars and other commutes will become smarter. With so many IoT projects, the future is bright. It has limitless potential in the future. Hyperscaling and advances to Industrial Internet will hyper-scale IoT to greater achievements.
