12V–24V DC PIR Sensor – Automate your lighting and enjoy hands-free convenience
Tired of leaving the lights on in the garage, hallway, or storage area? This 12V–24V PIR sensor is the perfect solution, offering easy installation without the need for complex wiring or electrical panel modifications. It detects movement, switches your lights on instantly, and turns them off automatically after your chosen time interval. Simple, reliable, and energy-efficient.
Note: This sensor is designed exclusively for 12V to 24V DC systems. It is not compatible with 230V AC mains power without an external converter.
Why choose this model? (Key Benefits):
- 12V and 24V DC Compatibility — Integrates directly into existing low-voltage systems without the need for extra adapters or transformers.
- 6A Maximum Current — Supports up to 72W at 12V or 144W at 24V, making it ideal for LED strips or compact lighting fixtures.
- Adjustable Timer (1–10 minutes) — Features an onboard potentiometer; set your desired duration in seconds—no apps or remote controls required.
- ≥ 5 Metre Detection Range — Provides wide coverage for standard corridors, garage entrances, or medium-sized offices without blind spots.
- Wide Operating Temperature (-20°C to +60°C) — Built to withstand both freezing conditions and the heat of industrial spaces.
- 4-Terminal Direct Connection — Simple 2-input, 2-output setup; no programming required. Perfect for DIY enthusiasts comfortable with DC wiring.
Performance and Technical Details
Using Passive Infrared (PIR) technology, this sensor detects changes in body heat. It is a passive device, meaning it doesn’t emit signals, avoids interference with other electronics, and consumes minimal power. It reacts specifically to human presence rather than drafts or ambient light changes.
With a detection range of at least 5 metres, it is perfectly suited for long hallways, garage entries, or storage rooms. Its compact 76 x 45 x 35 mm housing fits easily into standard distribution boxes or small enclosures without taking up unnecessary space.

Installation and Setup Guide
- Connect the input terminals to your 12V or 24V DC power source, ensuring you observe the correct polarity marked on the casing.
- Connect the output terminals to your lighting load: LED strips, spotlights, or other compatible fixtures.
- Use the timer potentiometer on the housing to set how long the light stays on after the last detected movement (1–10 minutes). Clockwise rotation increases the duration.
- Position the PIR sensor so the detection zone covers your target area effectively—ideally perpendicular to the main path of movement.
- Test the system by walking through the detection zone; the output should trigger immediately upon movement.

Frequently Asked Questions
Can this be used with 230V AC mains?
No. This device operates exclusively on 12V to 24V DC. For 230V AC applications, you would require a dedicated mains-voltage sensor or a suitable power converter.
What is the maximum load I can connect?
The maximum current is 6A. This equates to a maximum of 72W at 12V DC or 144W at 24V DC. Please do not exceed these limits to prevent overheating or device failure.
Does it work during the day?
Yes. PIR technology relies on body heat, not visible light. It does not have a built-in daylight sensor (LDR), so it will trigger the load regardless of ambient light levels.
Can it be installed outdoors?
While it is rated for temperatures between -20°C and +60°C, the casing is not IP-rated. For outdoor use, it must be installed in a sheltered location or inside a moisture-proof enclosure.
How do I adjust the timer?
There is a rotary potentiometer on the housing. Turn it clockwise to increase the duration (up to 10 minutes) and counter-clockwise to decrease it (down to 1 minute). No special tools are required.
