HCSR501 PIR Motion Sensor (Passive Infrared Sensor)

HCSR501 PIR Motion Sensor

The HC-SR501 PIR Motion Sensor Module used to detect the motion of a human body within the sensor’s range. It is often referred to as “PIR”, “Pyroelectric”, “Passive Infrared” and “IR Motion Sensor” sensors. The PIR Motion sensor module has an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens. 

The HCSR501 PIR Motion Sensor requires 4.5 ~ 20 DC voltage. This PIR sensor's tiny size and sturdy design make it ideal for a variety of applications, including burglar alarms, automatic lighting control systems, and DIY motion-sensing technology projects. 

This PIR sensor features an adjustable time delay function that allows for customization of the sensor's response time. This sensor is compatible with Arduino, Raspberry Pi, AVR, PIC, 8051, etc.
