#1616: HC-SR501 Adjustable Pyroelectric Infrared (PIR) Motion Sensor Module


The HC-SR501 adjustable pyroelectric infrared (PIR) motion sensor module is a device that is used to detect motion using infrared (IR) signals. It is a widely used module that is commonly found in a variety of applications, including security systems, home automation systems, and other applications that require the detection of motion.

The HC-SR501 module consists of a pyroelectric sensor that is able to detect the presence of a moving object by sensing changes in the level of infrared radiation in the environment. It is able to detect motion over a wide range of distances and angles, and it has an adjustable sensitivity level that can be set using an onboard potentiometer.

The HC-SR501 module is a reliable and widely used motion sensor that is easy to use and integrate into a variety of projects. It is often used in combination with other electronic components, such as microcontrollers and alarms, to build motion detection systems and devices.

Product Details

  • Product Type: HC--SR501 Body Sensor Module
