PIR Motion Sensor Module - HC-SR505

The HC-SR505 Mini Infrared PIR Motion Sensor is a compact and highly sensitive infrared detection module designed for various automatic control applications. Utilizing infrared technology, it operates with ultra-low voltage and is ideal for battery-powered devices. This module provides high reliability and precision in motion detection.

Technical Parameters:

Operating Voltage Range: DC 4.5V – 20V
Static Current: < 60μA
Output Level: High 3.3V / Low 0V
Trigger: Repeatable trigger (default)
Delay Time: Default 8 seconds ± 30% (customizable within decimal range)
PCB Size: 10mm x 23mm
Induction Angle: < 100-degree cone
Induction Distance: Up to 3 meters
Working Temperature: -20°C to +80°C
Sensor Lens Size: Diameter 10mm (default)

Specifications:

Automatic Induction: When a person enters the detection range, the output is high. When the person leaves, the output returns to low after the default delay. The sensor is ultra-small in size.
Repeatable Triggering: The sensor output remains high if there is continuous motion within the detection range. The output stays high until no further motion is detected, at which point it returns to low after the delay period.
Wide Operating Voltage Range: Operates within a range of DC 4.5V – 20V.
Low Power Consumption: Working current < 50μA, making it suitable for battery-powered automatic control applications.
Output Signal: High output signal that easily integrates with various circuits.
