Motion Detection Using Human Sensor Passive Infra Red (PIR)

This is my first idea for Arduino, and below I will tell you how this tool works. In this tutorial I will show you how to detect objects when we drive a car.

Step 1: Component and Setup

• One breadboard

• Speaker buzzer

• Motor DC

• LED

• Sensor passive infrared (PIR)

Step 2: How does it work

Sensors installed in the car will detect moving objects. This tool will only detect moving objects, that is, humans.

When the car was oncoming at a speed that fast, and then at the front there is a man who was crossing the street, the sensor will automatically detect the object and the sensor will send a signal through the module Bluetooth HC-05 in the form of sound installed in the car, then motorists will reduce the speed of the car. The sensors capture the distance reaches 100 to 300 meters.
