The PIR Motion Sensor Switch is a compact, contactless switching device designed to automatically control lighting and other compatible DC electrical loads when human movement is detected.

Using Passive Infrared (PIR) technology, the sensor detects changes in infrared radiation caused by moving people or other warm objects within its detection area.

Supporting 12V and 24V DC systems, the module offers a detection range of up to 8 meters, a sensing angle of approximately 60°, and an adjustable output delay from 1 to 10 minutes.

It is suitable for automatic lighting, motion-activated equipment, hands-free switching, and energy-saving automation projects.

Key Features

• PIR Motion Detection: Detects movement using passive infrared sensing technology.
• 12V/24V DC Operation: Compatible with supported low-voltage DC systems.
• Up to 8m Detection Range: Suitable for indoor motion-activated applications.
• 60° Detection Angle: Provides a defined motion detection area.
• Adjustable Delay: Built-in potentiometer allows output delay adjustment from 1 to 10 minutes.
• Contactless Switching: Activates connected equipment without requiring physical contact.
• Compact Design: Easy to integrate into electronic enclosures and automation systems.
• Energy-Saving Operation: Automatically controls connected loads based on detected movement.
• Terminal Connections: Screw terminals simplify power and load wiring.

Technical Specifications

Connection and Operation

Power Supply Connection

Connect the module to a compatible DC power supply:

• 12V System: Supply 10.5–16V DC.
• 24V System: Supply 21–32V DC.
• Load: Connect a compatible DC electrical load to the designated output terminals.

Operating Principle

1. Apply the appropriate DC power supply.
2. The PIR sensor monitors its detection area for movement.
3. When motion is detected, the module activates the connected load.
4. The load remains activated according to the configured delay.
5. The output switches off according to the module's timing behavior when motion is no longer detected.

Delay Adjustment

Use the onboard potentiometer to adjust the output activation time between approximately 1 and 10 minutes.

Applications

• Automatic LED Lighting
• Motion-Activated Cabinet Lighting
• Corridor and Staircase Lighting
• Hands-Free Lighting Systems
• Low-Voltage DC Automation
• Energy-Saving Lighting Projects
• Motion-Activated Equipment
• DIY Electronic Switching Systems
• Smart Home Automation Projects
• Workshop and Utility Lighting

Important Notes

• DC Operation Only: Use a compatible 12V or 24V DC power supply. Do not connect directly to 110V/220V AC mains.
• Maximum Load Current: Do not exceed the specified 6A switching limit.
• Connection Sequence: Connect the load before applying power to the module, following the manufacturer's wiring instructions.
• Correct Polarity: Verify the power supply polarity and terminal labels before powering the device.
• PIR Detection: The sensor detects changes in infrared radiation rather than measuring distance.
• Environmental Conditions: Detection performance may vary depending on ambient temperature, movement direction, installation position, and obstructions.
• Load Compatibility: Confirm that the connected equipment is suitable for the module's switching output.
• Not a Standalone Security Alarm: Additional equipment is required for audible alarms or remote notifications.
