PIR Motion Sensor Detector Module HC-SR501

If you want to build a device that is used to detect sense motion and almost always used to detect whether a human has moved in or out of the sensors range. Then this Sensor is needed for you.

The PIR Motion Sensor Detector Module HC SR501 allows you to sense motion. It is almost always used to detect the motion of a human body within the sensor’s range. It is often referred to using “PIR”, “Pyroelectric”, “Passive Infrared” and “IR Motion” sensors.

The module has an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens. It has a delay time adjustment Potentiometer and sensitivity adjustment Potentiometer. Compatible with ARDUINO, RASPBERRY PI, AVR, PIC, 8051, etc.
