HC-SR501 Motion Detector Pyroelectric Infrared sensor PIR (Passive Infrared sensor)

Description

The HC-SR501 human body PIR sensor is an efficient and reliable pyroelectric infrared sensor. This cutting-edge sensor is designed to detect human movement and can be used in a range of applications, including security and home automation. The passive infrared sensor (PIR) sensor module is used for motion detection. It is often referred to as 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 is used to sense the movement of people, animals, or other objects. They are commonly used in burglar alarms and automatically activated lighting systems.

It is a brand-new HC-SR501 sensor module with a 5-to-20-volt operational range. Its high value is 3.3V, while its low weight is 0. (It is on or off.). The detection distance can be changed from 3 to 7 meters, and the delay duration can be altered from 5 to 200 seconds. The sensor measures 32 mm by 24 mm across the board (standard Pir motion sensor). The sensor will send a high level of 3.3V when motion is detected and resume or keep sending a 0V when no motion is detected. If you’re using a microcontroller, you can power the sensor using a 3.3-volt supply or a 5-volt supply pin (VCC).

One of the critical features of the HC-SR501 human body PIR sensor is its ability to accurately sense infrared radiation and movement. It also has a range of up to 5 meters and an angle of 120 degrees, making it perfect for large spaces. This sensor is also highly sensitive, so it can easily detect even the slightest movements. The HC-SR501 human body PIR sensor is a compact and durable device. It can be easily installed and used with a range of microcontrollers and other electronics.
