PIR Motion Sensor Detector Module HC-SR501 |PIR sensor |Motion Sensor | radiomarket.in

The HC SR501 PIR Motion Sensor Detector Module is a crucial component for detecting motion, especially human movement, within its sensing range. Featuring a pyroelectric sensor, integrated conditioning circuitry, and a dome-shaped Fresnel lens, this module offers reliable and accurate motion detection. Often referred to as a “PIR,” “Pyroelectric,” “Passive Infrared,” or “IR Motion” sensor, it is specifically designed to detect human presence and motion. Whether you’re developing a security system, automated lighting, or any other motion-sensitive application, the HC SR501 PIR Motion Sensor Module is an essential tool for your project.

Product Description

To connect it to any microcontroller, power the device with 5V and GND pin from your controller like Arduino, Raspberry Pi, PIC, etc. Connect the output pin to any GPIO pin of your controller and go through your intended program. Adjust the sensitivity and time delay as per your liking from the two potentiometers provided on the module. You can also select the mode whether you want the output to remain high or go low after a specific time when a motion is detected.
