PIR Motion Sensor Module HC-SR501 (Human and Animals Motion Detector Sensor) (1 Pcs)

Product Details of PIR Motion Sensor Module

The PIR Motion Sensor Module HC-SR501 is a commonly used sensor for detecting motion based on infrared radiation emitted by a moving object within its detection range. It operates at a 5V DC supply voltage and consumes very low quiescent current (<50 µA) in standby mode, making it suitable for battery-powered applications.

The sensor module detects motion within a cone angle of less than 120 degrees and can detect movement at distances ranging from 3 meters to 7 meters (adjustable via onboard potentiometers). Upon detecting motion, it provides a digital output signal (high or low) that can be read by a microcontroller or used to trigger other electronic devices.

The HC-SR501 module features adjustable delay time settings, allowing you to customize how long the output remains active after motion is detected (adjustable from 0.3 seconds to 5 minutes). It also offers a choice between repeatable and non-repeatable trigger modes, giving flexibility in different applications.

This PIR motion sensor module is widely used in security systems, automated lighting controls, intruder alarms, and various motion-activated applications where detecting human or animal motion is necessary for triggering actions or alerts.

In summary, the HC-SR501 PIR Motion Sensor Module provides reliable motion detection capabilities with adjustable parameters, making it a versatile choice for integrating motion sensing functionality into electronics projects and home automation systems.
