Home Automation using Arduino

Arduino is one of the most popular open-source hardware prototyping devices. There are lots of projects developed using Arduino. Home Automation is also one of the most developed projects.

Through this project, you could able to automate the lights and siren.

If someone enters the room then light automatically turned ON, if a gas leak from the kitchen then siren and red led turned ON to alert you, and finally you could make a safe parking room if someone tries to theft your automobiles then siren turned ON and alert you.

So in this project named Arduino Home Automation, we are going to use sensors like Ultrasonic, PIR Motion Sensor, MQ-2 Gas Sensor, and different actuators like Buzzers, LEDs, etc.

3 Steps then see the Magic

Step 1: Setup

We do not need to set up a bunch of tools just install Arduino IDE for Code, Debug, and Burn the Code into IC.

Step 2: Code

Step 3: Wiring

To develop this project we are going to use these components :

• Arduino Uno
• PIR Motion Sensor
• Ultrasonic Sensor
• MQ-2 Gas Sensor
• Buzzer
• LEDs
• Breadboard
• Jumper Wire
