Best IoT based Projects

If you are seeking IoT project ideas, we have compiled a selection of the most fascinating IoT projects for both beginners and experts. These cutting-edge IoT projects will provide you the experience you need to become industry-ready and develop your career.

IoT Based Smart Agriculture System

IoT Based Smart Agriculture System

This system, which is powered by Arduino, consists of wireless sensor networks that collect data from various sensors at various nodes and transfer it via the wireless protocol.

A temperature sensor, moisture sensor, water level sensor, DC motor, and GPRS module are also included to deliver information about agriculture areas. All information is displayed on an LCD screen, and users are notified via SMS alerts on their smartphones.

This is a fantastic IoT project for newcomers. This smart agricultural system allows you to use your smartphone to monitor soil moisture, humidity, and water level, as well as automatically irrigate a piece of land and spray fertilizers or pesticides.

IoT Based Air Pollution Monitoring System

IoT Based Air Pollution Monitoring System

Noise and air pollution levels are increasing in metropolitan areas, and they must be addressed soon. Air and noise pollution can be monitored using an IoT-powered air and noise pollution monitoring system. This information can be saved on web servers and used later.

The system is made up of air sensors that detect dangerous chemicals and compounds in the atmosphere. It also keeps track of sound levels and sends data to an online server.

The sensors communicate with the microcontroller, which sends the information over the internet. Authorities can utilize the data to adopt pollution-control actions based on the information.

Water Level Sensor

Water Level Sensor

Sensing the level of water in a container is another use for the internet of things, which might be especially handy for pet owners who forget to refill their pet’s water bowl.

This IoT-based device detects the amount of water in a tank, and the project’s designer got the idea after miscalculating the amount of water in their home’s water tank.

An ultrasonic distance sensor is attached to a Raspberry Pi board in this project. Once the project’s source code is installed onto the Pi, the device should be able to detect the amount of water in a tank.

When the amount is recognized, the Pi converts the information into a graphical display on an online interface that anybody may access.

Baggage Tracker

Baggage Tracker

When you state that only 1% of baggage is lost during plane travel, it seems like a little percentage. When we look at absolute figures, though, 1% of billions of travelers is still a significant amount. It is possible that the next bag they misplace is yours.

This project creates a mechanism that allows you to track your luggage even while it is in the air. Build it, toss it in your bag, and you will be able to keep track of everything from your phone.

Gesture-Controlled Contactless Switch for Smart Home

Gesture-Controlled Contactless Switch for Smart Home

The goal of this IoT project is to create a gesture-controlled switch that can be used in both homes and public spaces. You will need an Arduino mini pro, an OLED display, a Channel Relay, a 5V converter, a Gesture Sensor, and a lamp for this project.

The gesture sensor detects motions in its immediate surroundings and translates them into commands for operating the light bulb or other electric appliances in the home. It is a straightforward but intriguing project. It is worth a shot.

Attendance System

rfid ioa

Utilizing authentication devices to authenticate identification, this IoT gadget is a terrific approach to take attendance. This could be beneficial in companies and schools to determine who is attending and arriving on time for an event.

Once put together, you will have a handy IoT attendance system that tracks when someone signs in using their RFID tag. You can also create an online interface to examine the number of users, attendees (those who signed in), and the ID number of each user.

This project necessitates a large number of components, including radio frequency identification (RFID) tags, an RFID reader, a Raspberry Pi board, a breadboard, and other tools.

The instructions of the project say to use a Raspberry Pi 2, 3, or 3 B+ for this project; however, the comments say that other models would work as well.

Health Monitoring System

IoT technology can also be utilized to save many lives in the healthcare industry. The Internet of Things-based Health Monitoring System is a fantastic IoT project that can assist patients in keeping track of their own health.

This technology allows users to keep track of their bodily vitals such as blood pressure, sugar level, and heartbeat and send the information to healthcare providers over the internet. Patients can receive timely advice from healthcare professionals based on their health status.

Several sensors, a microprocessor, a Wi-Fi connection, and an LCD screen make up this system. If the system detects any sudden changes in a patient’s vitals, it sends an email to the user/healthcare professional informing them of the patient’s condition.

Car Parking Management System

Car Parking Management System

Car parking is one of the most pressing challenges in today’s cities. There is a need for an effective car parking management system that can aid in the resolution of the parking situation.

IoT can assist in the creation of such a system. IoT-based automobile parking management systems aid in the efficient use of parking spaces.

It makes use of infrared sensors, dc motors, a Wi-Fi modem for internet access, and an AVR microprocessor to control the device. The IR sensors detect if a parking space is occupied, and the dc motors act as gate opener motors.

The system refreshes data on the cloud server by checking the number of available parking spaces. This method allows you to see available parking spaces online from anywhere and drive straight to them.

Remote Plant Monitor – IoT Home Automation

IoT Home Automation

This Internet of Things project will detect dry soil and notify you when the plant requires watering. There are two sections to the project.

The moisture detecting system, which monitors when the soil becomes dry, is the first part. When the system identifies dry soil, it sends a signal to the project’s second phase.

The second section has a servomotor with a flag and a limit switch. As soon as the signal reaches the second part, the servo motor switch is activated, and the flag begins to rise to alert you to the problem.

Mail Detector

 Have you ever wanted to know if you have received a box when you are not at home? This Internet of Things device can identify if you have received mail, which is ideal for ensuring that your shipments arrive on schedule and safely into your mailbox.

The creator of this project shows how to put the hardware together, including how to connect the sensors to the breadboard’s GPIO ports.

The project uses Twilio, a cloud service provider, to send the collected data to other devices, and the guide walks you through the basics of setting up the connections.

This mail detector project requires a Raspberry Pi 3 and a few more components such as a breadboard, a laser, and a motion sensor.

Your Pi should be able to identify when the mailbox door is opened and an object enters the area after it is up and running. When your Pi’s motion sensor is triggered, you can configure the device to send you a text message.
