Through this post, you’ll learn how to make some of the top IoT Projects using Arduino. The easy-to-understand content of this blog will give you a good idea of basic concepts and applications of IoT. All the IoT projects using Arduino mentioned in this post are selected based on the application, implementation, and complexity involved.
Before heading on to the projects, lets first understand what’s IoT. The Internet of Things or IoT implies the interconnection of various electronic devices through the internet, continuously monitoring, tracking, sharing, or collecting data. The emergence of IoT has helped mankind take a giant leap forward.
First of all the sensors, processors, and communication hardware helps us to collect the data. This collected data is then either sent to the cloud to look over. Finally, the device/sensor makes the required adjustments as per the analyzed data.
This way IoT creates an environment for effective resource utilization to minimize human effort which ultimately saves time and improves security.
With all the above things considered, here we present the Top 10 selected IoT projects using Arduino.
Smart Bin

OBJECTIVE:
This is an innovative project that operates efficiently to provide a solution to disposing of garbage problems using IoT and mic sensor circuit. The ultrasonic sensor continuously monitors the garbage level in the bin. When the bin is full, the circuit raises an alarm and alerts the user, so that the user can be empty and reuse the bin again.
Components required for the project are:
- Arduino Uno
- Ultrasonic sensor
- Mic sensor
- Wi-Fi module
- Capacitors
- Resistors
- Transistors
- PCB and breadboard
- Cables and connectors
- LED
- Transformer/Adapter
Weighing scale

OBJECTIVE:
Using this project, we can measure and monitor weights from any part of the world. The load cell (strain gauge) used here is of 5 kg. A to D converter converts the physical weight to corresponding digital signals and sends it to the owner with the aid of Arduino.
Components required for the project are-
- Arduino Uno
- Load cell (Strain gauge)
- Wi-Fi module
- Transistor
- Resistors
- Capacitors
- Analog to digital converter
Gas Detector

OBJECTIVE:
A simple and economical project that alerts the user if there is any gas leakage in household premises. The gas sensor in the circuit detects quickly senses the butane gas which triggers an alarm in the circuit along with the message signal sent to the owner over the internet.
Components required for the project are:
- Arduino Uno
- Wi-Fi module
- Gas sensor
- Connecting wires
- PCB board
- Buzzer
- Switch
Food spoilage detector

OBJECTIVE:
This project regularly tracks and monitors the quality of food in our household. The gas sensors sense the smell of spoiled food and relay a message to the Arduino. Arduino flashes the message on the LCD display that the food is spoiled. Along with this, the owner also receives a message for the same.
Components required for the project are:
- Arduino Uno
- Wi-Fi module
- Gas sensor
- LCD display
- Power supply
- Alarm
- Connecting wires
Attendance system

OBJECTIVE:
This project demonstrates a smart way for the attendance system. The RFID scanner scans the RFID cards and logs the data to a cloud platform with the help of the Wi-Fi module hence recording the attendance of the student to whom the card belongs. You can check the recorded attendance on the internet at any time.
Components required for the project are-
- Arduino
- Wi-Fi module
- RFID scanner
- Breadboard
- Connecting wires
- RFID cards
Tech Arm

OBJECTIVE:
This project demonstrates a robotic arm with universally accessible control. The project is suitable for the places where human reach is difficult or not possible. With the record and repeat mode, the same task can be performed over and over again with the same efficiency and speed.
Components required for the project are-
- Arduino
- Wi-Fi module
- Servo motors
- Motor driver
- Connecting wires
- Holding clamp
- Indication LED
Water quality monitoring

OBJECTIVE:
This project regularly monitors and tracks the pH value of the water and fitness of water. The range of pH between 7.2 and 7.8 is considered fit for drinking purposes. The pH value of water is periodically updated to the owner over the internet.
Components required for the project are-
- Arduino
- pH sensor
- pH meter
- Wi-Fi module
- Connecting wires
- Transistor
- Capacitors
- LED
- Resistors
Car Parking System

OBJECTIVE:
This project demonstrates the use of an IR sensor to regularly monitor free space in the car parking area. As soon as a vehicle comes within or leaves the proximity of an IR sensor, the information is sent via the internet to the authority and hence the vacant and filled parking slots can be known at any time.
Components required for the project are-
- Arduino
- IR sensor
- Wi-Fi module
- Power Supply
- Connecting Wires
Health Monitor

OBJECTIVE:
It’s a simple and economical project to monitor a person’s health from a remote place. The temperature sensor senses the temperature of the human body while the pulse sensor measures the contraction and relaxation of the blood capillaries. Both these data are uploaded and stored on the cloud. A doctor can easily access this data from anywhere.
Components required for the project are-
- Arduino
- Wi-Fi module
- Pulse sensor
- Temperature sensor
- LCD display
- Resistors
- Breadboard
- Connecting wires
- LED
LPG detector and auto exhaust

OBJECTIVE:
This project demonstrates a smart way to tackle the gas leakage problem. The gas sensor quickly senses any leakage of gas and according to the level of gas as low, normal, or high and takes corresponding steps simultaneously by notifying the owner and turning ON the exhaust fan. The exhaust fan turns OFF automatically as the gas level falls down.
Components required for the project are-
- Arduino
- Wi-Fi module
- LCD display
- DC fan
- PCB
- Capacitors
- Resistors
- Adapter
- LED
- Connecting wires
