Top 10 Arduino IOT Projects

The “Internet of Things” (IoT) is a huge network of connected electronic devices that collect data and share it without any help from a person.

Arduino has a wide range of development boards, from 8-bit to 32-bit microcontrollers, including those that work with Bluetooth and WiFi. This, together with the beginner-friendly projects it offers online, makes Arduino the perfect platform for starting your first Internet of Things project!

However, to pick out your skillful side, we have listed ten IoT projects you can make with Arduino boards. So, let’s take a look at them. 

Top 10 Arduino IoT Projects

Here are the top 10 Arduino projects you should try out:

1) Smart Bin

To keep the track of your garbage, a smart bin is your best bet. It will track how full a trash can is at any moment. So, trash collectors may be able to better plan when they pick up trash, which makes waste collection more efficient and uses less fuel.

For this project, you’ll need Arduino WiFi Shield 101 and Arduino 101. The ultrasonic sensor used in this project will continuously monitor the level of trash n your bin. Additionally, the circuit attached sounds an alarm and notifies the user when the trash can is full, allowing for quick emptying and subsequent reuse. 

However, there is more rubbish in and around urban areas due to population growth. For this, we suggest an IoT ingenious dustbin that automatically uses sensor-based electronics to solve this problem. 

However, to start this project, the components required for a smart bin are:

  • Ultrasonic sensor with Arduino Uno
  • connections and cables
  • Mic detector
  • Capacitors
  • Resistors
  • Wi-Fi component
  • Breadboard with PCB for transistors
  • LED\sTransformer/Adapter

2) Weighing Scale

With the help of a weighing scale using Arduino IoT projects, you can measure and keep a record of weights from any location in the world. Besides this, the application uses a load cell rated at 5 kg (strain gauge). An analog-to-digital converter (A-to-D converter) is connected to an Arduino. Moreover, it is one of the best IoT projects and is responsible for converting the actual weight into the proper digital signals. Once the person steps on the machine, the weight is displayed on the LCD.

Nevertheless, the supplies that you will need for this project are: 

  • Load cell (Strain gauge)
  • WiFi module for Arduino Uno
  • Capacitors
  • Resistors
  • Transistors
  • Digital to analog converter

3) Gas Detector

An easy-to-implement and low-cost project that provides users in residential areas with early warning of gas leakage. The butane gas is detected very instantly by the circuit’s gas sensor, which then triggers an alarm and communicates with the owner of the device over the internet.

However, for this project, you’ll need

  • Wire connections for an Arduino Uno Wi-Fi 
  • module gas sensor
  • Buzzer or switch
  • PCB board

4) Water quality monitoring

As part of this experiment, the pH level of the water, as well as its general condition, will be carefully tracked. The experts suggest that drinking water should have a pH between 7.2 to 7.8. Therefore, water quality monitor, will keep the track of your drinking water’s pH level.

Other than this, the internet provides the proprietor with up-to-date information on a daily basis regarding the pH level of the water.

However, project-related elements that are needed include

  • Arduino pH meter and sensor
  • Wi-Fi component
  • LEDs
  • Resistors
  • Transistors
  • Capacitors
  • Assembling wires

5) Food spoilage detector

This initiative monitors and assesses the quality of the food we keep in our homes constantly. However, when the gas sensors detect an odor consistent with spoiled food, they warn the Arduino. Also, once your food turns bad, the LCD screen on Arduino will display the information about your spoiled food.

The components required for the project are:

  • Uno Wi-Fi module for Arduino
  • Alarm Gas sensor 
  • LCD display
  • Power source
  • Assembling wires

6) A Sunlight Monitoring Panel

One green energy source is solar power. It is very significant in the modern world. We will become even more reliant on this type of renewable energy as our access to carbon-based fossil fuels dwindles. Additionally, our global warming and carbon footprint are increasing at an alarming rate.

So, whether you already have a large-scale solar farm, are building a tiny one, or just appreciate solar energy in general, you might be interested in this. No matter who you are, you would require a solar panel. Additionally, if you have solar panels installed, you are throwing away a lot of potential energy because the panels don’t move with the sun throughout the day.

However, for this project, you will need the following: 

Moreover, making your solar panels, you could monitor the amount of solar energy in your region and determine which position would produce the most energy.

Also, you wouldn’t need a lot of equipment and wouldn’t be spending much money. However, you may significantly impact how much money you would ultimately create with such a modest sum of cash.

7) Tech Armor

This entire design demonstrates a robotic arm that anyone or everyone controls. Moreover, this plan is suitable for remote or inaccessible areas that are difficult or impossible for humans to reach. Furthermore, using the record and repeat function, the robotic arm makes it possible to carry out the same task multiple times with the same efficiency and velocity.

However, to start the project, the components required are the following

  • Wi-Fi Arduino module
  • Robotic motors
  • Driving a vehicle while tying wires
  • Holding clamp LED indicator

8) Car Parking System

The efficient use of parking spaces is made possible by this cutting-edge car parking system. Also, finding a parking spot is challenging. Additionally, this security system uses sensors to monitor for open slots, update the status over the internet of things, and send out alerts. 

There are two gates: an entrance and an exit. As soon as the sensor identifies your car, the gate opens. Moreover, the Atmega328 processor powers this system, which includes a DC motor, IR, and LCD transmitter and receiver. 

However, when IR sensors are installed at a parking garage’s entrance and exit, the doors can be opened automatically, and barriers can be lifted whenever a car approaches or leaves the garage. Therefore, using this technique, the parking system can be automated without needing staff.

This project shows how an IR sensor can continuously monitor open spaces in a parking lot. By using infrared (IR) sensors, the number of open and taken parking spots can be determined in real-time through the internet as soon as a car enters or exits the area covered by the sensors.

However, to start this project, you will need the following: 

  • IR sensor
  • Arduino Power source
  • Connecting wires
  • WiFi module

9) Attendance system

This project demonstrates an innovative strategy for handling the attendance process. The Wi-Fi module contained within the RFID scanner is responsible for reading RFID cards and uploading the data to the cloud, which is then linked to the attendance record of the relevant student. Moreover, you can also view the attendance information online at any time.

However, the project-related elements that are needed include

  • Arduino board
  • Wi-Fi component
  • Breadboard
  • an RFID reader
  • An RFID card

10) Health Monitor

Keeping track of someone’s health from a distance is straightforward and affordable. The human body is quite complicated, and to simplify the process, a health monitor will help you monitor your vitals easily.

While the pulse sensor tracks the expansion and contraction of blood capillaries, the temperature sensor detects the human body temperature. Both of these data are uploaded to the cloud and kept there. This information is readily available to doctors everywhere.

However, to start this project, the components required are the following

  • Wi-Fi Arduino module
  • Temperature sensor
  • LCD display
  • Resistors
  • Breadboard
  • Assembling wires
