PIR Motion Sensor Light Switch – Adjustable AC 110–240V
PIR Motion Sensor Light Switch – Adjustable AC 110–240V
Hands-Free Lighting with Smart PIR Motion Detection
Take control of your home or office lighting with this compact, high-sensitivity PIR (Passive Infrared) Motion Sensor Light Switch. Designed for AC 110–240V systems, it automatically turns lights on when it detects movement and switches them off after a set delay — saving energy and adding genuine convenience to any space. Made in Mainland China.
Key Features
- Wide Detection Range: 160° field of view with a detection distance of 3–8 meters (at 25°C), ideal for hallways, stairwells, bathrooms, garages, and more.
- Adjustable Ambient Light Sensitivity (LUX): Set the sensor to operate 24/7 (day mode) or only at night (night mode) using the simple LUX dial — perfect for energy-conscious setups.
- Adjustable Delay Timer: Choose how long the light stays on after motion stops — from 10 seconds up to 5 minutes — so your lights are never left on unnecessarily.
- Adjustable Sensitivity (SENS): Fine-tune the sensor's responsiveness to suit your environment and avoid false triggers.
- Universal Voltage Compatibility: Works on AC 110–240V, suitable for both US and international electrical systems.
- Compact & Easy to Install: Small 42×40×20mm body fits standard open-type mounting (10mm opening). Recommended installation height: 1.8m–2.5m.
- Durable Construction: Flame-retardant ABS plastic casing with a Fresnel lens for efficient, wide-angle infrared detection.
- CE Certified: Meets European safety and compliance standards for high-voltage electronics.

How the Controls Work
- LUX Dial: Rotate toward the sun icon for all-day operation; rotate toward the moon icon to restrict operation to nighttime only.
- TIME Dial: Sets the delay period — the length of time the light remains on after the last detected movement in the sensing area.
- SENS Dial: Adjusts detection sensitivity. If lights trigger too easily, reduce the sensitivity to the minimum setting.
Ideal Applications
- Hallways, corridors, and stairwells
- Bathrooms and laundry rooms
- Garages and storage rooms
- Outdoor covered porches and entryways
- Offices and commercial spaces

Frequently Asked Questions
Q: What voltage is this PIR motion sensor light switch compatible with?
A: This motion sensor switch supports AC 110–240V, making it compatible with standard US household wiring (110V) as well as international systems up to 240V.
Q: Can I use this motion sensor switch outdoors?
A: The switch can be used in covered outdoor areas such as porches or carports where it is shielded from direct rain. It is not rated for fully exposed outdoor installation. Operating humidity must remain below 93% RH.
Q: How do I stop the light from staying on all day?
A: Simply turn the LUX dial to the moon icon position. This tells the sensor not to activate during daylight hours, so the light will only switch on automatically when ambient light drops below your set threshold at night.
Q: What is the maximum load wattage for this switch?
A: The switch supports a maximum load power of under 100W at a rated current of 4A. It is suitable for standard LED, CFL, and incandescent bulbs within this power limit.
