Circuit Diagram
In this circuit, the PIR sensor detects the motion and sends the digital value to the Arduino and Arduino sends the signal to the Serial Monitor and the buzzer will be started. otherwise, it will be off.
How to make Motion Detection System using Arduino?
Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards can read digital & analog inputs from the sensors and The PIR sensor is a special type of sensor which is usually used for security purposes. It detects the objects by reading the Infrared radiations emitted by the objects. Any object whose temperature is above absolute zero emits radiation. This radiation is not visible to human eyes. The PIR sensor is designed to detect this Infrared radiation.
In this article, We will learn how can we make a Motion Detection System using Arduino. When the PIR Sensor will detect any motion, it will show that on the Serial Monitor and the buzzer will start.
