The PIR Motion Sensor Detector Module HC-SR501 is a commonly used device for detecting human movement within its range. It operates based on passive infrared (PIR) technology and is widely used for security, automation, and robotics applications. It detects infrared radiation emitted by humans or animals, triggering an output signal when motion is detected.
Features:
Infrared Sensor with Control Circuit Board: The module contains both the sensor and a control circuit for motion detection.
Adjustable Sensitivity and Holding Time: You can adjust the sensitivity (detection range) and the time the sensor stays active after detecting motion.
Blockade time: Default is 2.5 seconds.
Sensitive Setting: Turn to the right to increase detection distance (up to about 7 meters), and turn to the left to reduce the detection distance (down to about 3 meters).
Time Setting: Turn to the right to increase the time (up to about 200 seconds), and turn to the left to decrease the time (down to about 5 seconds).
Compact Design: It comes in a compact design and is easy to integrate into various projects.
 Notes:
Color Variants: The product is available in two colors: blue and green. The packaging may contain either of the colors.
Common Applications: This module is ideal for creating automated systems like motion-triggered lighting, security alarms, and other devices that require human motion detection.
Package Includes:
1 x PIR Motion Sensor Detector Module HC SR501
