PIR Motion Sensor Light Switch – Auto On/Off, DC 3V–30V
PIR Motion Sensor Light Switch – Auto On/Off, DC 3V–30V
PIR Infrared Motion Sensor Light Switch
Take control of your lighting automatically with this smart PIR (Passive Infrared) Motion Sensor Light Switch. Designed for both indoor and outdoor use, this intelligent sensor switch detects human body heat and triggers your lights to turn on instantly when someone enters the detection zone — and automatically shuts them off after the person leaves. Perfect for hallways, staircases, garages, bathrooms, kitchens, balconies, warehouses, and solar-powered lighting systems.
Why You'll Love It
- Automatic Hands-Free Control: Lights turn on when you arrive and off when you leave — no more fumbling for switches in the dark.
- Energy Saving: Only activates lighting when it's truly needed, helping reduce unnecessary electricity consumption.
- Wide Voltage Compatibility: Works with DC 3V–30V power sources, including solar-powered spotlights and floodlights.
- Adjustable Detection Range: Sensing distance of 2m–12m (varies with ambient temperature) with a 120° adjustable induction angle.
- Adjustable Delay Time: Set your preferred light-off delay from 5 seconds up to 2 minutes to suit your environment.
- Light Control Mode: Built-in dusk-to-dawn functionality — the sensor only activates in low-light or dark conditions, preventing unnecessary daytime triggering.
- Easy Installation: Panel-mount design with opening sizes of 16mm, 12mm, or 10mm. Install with the adjustment button facing downward for optimal weather resistance.
- Durable Construction: Made from robust ABS plastic, built to withstand everyday use.

Frequently Asked Questions
Q: What voltage does this PIR motion sensor light switch support?
A: This sensor switch operates on DC 3V to 30V, making it compatible with a wide range of DC power sources including 3.7V, 5V, 12V, and 24V systems, as well as solar-powered spotlights and floodlights.
Q: Can I adjust the detection range and delay time on this motion sensor switch?
A: Yes! The sensing distance is adjustable from 2 meters up to 12 meters (depending on ambient temperature), the induction angle is adjustable up to 120°, and the light-off delay time can be set anywhere from 5 seconds to 2 minutes to suit your specific needs.
Q: Will this PIR sensor switch activate during daytime or in bright conditions?
A: No. This switch features a built-in light control (dusk-to-dawn) mode, which can be configured so the sensor only triggers in low-light or dark environments — preventing unnecessary activations during daylight hours.
Q: Where can I install this motion sensor light switch?
A: It is suitable for a wide variety of locations including bathrooms, kitchens, hallways, staircases, garages, balconies, warehouses, corridors, and outdoor solar lighting setups. It requires a panel cutout of 16mm, 12mm, or 10mm depending on your installation type. For best weather resistance, install with the adjustment button facing downward.
