PIR Motion Sensor

HC-SR501 Passive Infrared (PIR) Motion Sensor

The HC-SR501 is a highly reliable PIR sensor module designed to detect human or animal movement by sensing changes in ambient infrared radiation. Equipped with a multifaceted Fresnel lens and an onboard BISS0001 controller IC, it offers highly tunable sensitivity and time-delay adjustments for precise security and automation deployments.

• Detection Range: Up to 7 meters (110-degree cone)
• Operating Voltage: 4.5V to 20V DC
• Adjustments: Dual potentiometers for Sensitivity and Trigger Time Delay
• Common Use Case: Automated security lighting, intelligent home alarm systems, and interactive museum exhibits.
