PIR Motion Sensor Module HC-SR501

The Passive Infra-Red (PIR) sensor is a motion detection device that senses changes in infrared radiation emitted by objects in its surroundings. When motion is detected, it outputs a HIGH signal on its I/O pin. It is commonly used in security systems to monitor areas such as rooms or halls for human presence.

Features:

• Operating voltage: 5–20V DC
• Digital single-bit output
• Adjustable delay time
• Works with all types of microcontrollers
• Compact design for easy concealment
• Plug-and-play functionality
