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

R 39.20 In Stock (4)

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.

Note: The potentiometer clockwise to adjust the distance, sensing range increases (about 7 meters), on the contrary,
sensing range decreases (about 3 meters).Delay adjustment potentiometer clockwise rotation, sensor delay longer (about 300S),
the other hand, induction by the short delay (about 5S).
