The HC-SR501 PIR Sensor is a reliable and easy-to-use module for motion detection. It works by measuring infrared (IR) light radiating from objects in its field of view. When a human or animal passes by, it triggers a high signal, making it ideal for Arduino and Raspberry Pi projects.
Key Features:
-
Adjustable Sensitivity: Built-in potentiometer to control the detection distance (up to 7 meters).
-
Adjustable Delay Time: Control how long the output stays HIGH after motion is detected (from 5 seconds to 5 minutes).
-
Wide Voltage Range: Operates on 4.5V to 20V DC.
-
Detection Angle: Wide 120-degree cone detection.
-
Two Trigger Modes: Choose between single trigger (L) or repeatable trigger (H) using the onboard jumper.”
