DC 12V PIR Motion Sensor Switch – Adjustable Delay, Relay Output (5–8m Range)
General

• Product Type: PIR Motion Sensor Relay Module
• Detection Type: Infrared (Human Body Detection)
• Sensor Technology: Pyroelectric Infrared (PIR)

Power Supply

• Operating Voltage: DC 12V
• Working Current: < 50mA
• Power Input: Red (+) / Black (-) wires

Output

• Output Type: Relay (switch output)
• Output Voltage: Same as input (12V output on trigger)
• Load Capacity:
  • Up to 10A (relay rating, depends on load type)
• Output Wire: Yellow (trigger output +)

Detection Performance

• Detection Range: 5 – 8 meters
• Detection Angle: ~120°
• Trigger Mode:
  • H (Repeatable): Keeps output ON while motion continues
  • L (Non-repeatable): One-time trigger per detection

Time Delay Adjustment

• Delay Time: ~10 seconds to ~5 minutes
• Adjustment Method: Onboard potentiometer
  • Turn clockwise → longer delay
  • Turn counterclockwise → shorter delay

Wiring

• Red Wire: Power + (12V)
• Black Wire: Power – (GND)
• Yellow Wire: Output + (to load)

Features

• Automatic motion detection (no contact required)
• Adjustable delay timer
• Repeatable / non-repeatable trigger modes
• Compact design with external PIR sensor
• Easy installation with pre-wired cables

Applications

• Automatic lighting systems
• Security alarms
• Corridor / staircase lights
• Energy-saving automation
• Smart home DIY projects

 Important Notes

• Designed for human motion detection only (not precise object detection)
• Avoid direct sunlight, heat sources, or airflow interference
• Install at proper height (~2–3 meters) for best performance
