The PIR Motion Sensor Detector Module HC-SR501 is designed to detect motion, primarily the movement of a human body within its range. It’s commonly known as a “PIR,” “Pyroelectric,” “Passive Infrared,” or “IR Motion” sensor.
This module features an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens. It includes a potentiometer for adjusting delay time and another for sensitivity. It is compatible with platforms such as Arduino, Raspberry Pi, AVR, PIC, and 8051, making it versatile for various applications.

Note: The Product available in Two colors Blue and Green, therefore packing you may get any one of them.
Features:
Infrared Sensor with Control Circuit Board
The Sensitivity and Holding Time is adjustable.
Blockade time: 2.5s (Default)
Sensitive Setting: Turn to Right, Distance Increases (About 7M); Turn to Left, Distance Reduce (About 3M)
Time Setting: Turn to Right, Time Increases (About 200S); Turn to Left, Time Reduce (About 5S).
The PIR Motion Sensor Detector Module HC-SR501 is a versatile pir / ir and optical sensor used across a wide range of applications including motion detection, security systems, automatic lighting, people counting, and gesture recognition.
Common use cases:
Building an automatic porch light
Creating a people counter for a room
Adding motion detection to a security system
This product is ideal for home automation builders and security system designers.
Technical Tip: PIR sensors detect heat-emitting movement. Adjust sensitivity and delay potentiometers for your environment. False triggers can be reduced with proper shielding.
