Mini PIR Infrared Motion Sensor Switch – Automatic Night Lighting
Never fumble for a light switch in the dark again. This compact PIR (Passive Infrared) Motion Sensor Switch automatically turns lights ON the moment it detects movement in low-light conditions, then switches them OFF after 30 seconds of inactivity — saving energy effortlessly. Ideal for hallways, staircases, bathrooms, basements, garages, closets, and warehouses.
Made in Mainland China.
Key Features
- Automatic Motion Detection: 120° wide-angle sensing detects human body heat up to 3–5 m away (maximum range up to 6 m).
- Night-Only Operation: Built-in light control activates only in darkness or when ambient light falls below 10 LUX — no false triggers during the day.
- 30-Second Auto-Off: Lights switch off automatically 30 seconds after motion is no longer detected, keeping energy use to a minimum.
- Wide Voltage Compatibility: Works with standard AC 85–265 V power supplies, compatible with most global electrical systems.
- Compact & Lightweight: Measures just H 37.2 mm × D 27.5 mm and weighs only 11.8 g — easy to fit into tight spaces.
- Plug & Play Wiring: Link terminal design makes installation and future replacement simple — no specialist tools required. Supports both embedded and surface-mount fitting (mounting hole diameter: ⌀20 mm).
- Versatile Control: Controls LED ceiling lamps, energy-saving bulbs, incandescent lamps, and even exhaust fans, doorbells, and other low-load devices.
- Flame-Retardant PC Shell: Durable, heat-resistant polycarbonate casing ensures long-lasting, safe operation.

Frequently Asked Questions
Q: Will this PIR motion sensor switch work during the day?
A: No — the built-in light control function means the switch only activates in low-light or dark conditions (below 10 LUX). During daylight hours it remains inactive, so you won't get unnecessary light switching during the day.
Q: What types of lights and devices can this motion sensor switch control?
A: The PIR sensor switch is compatible with LED ceiling lamps, energy-saving bulbs, and standard incandescent bulbs — as long as the total load is 40 W or less. It can also be used to control low-wattage exhaust fans, doorbells, and similar devices within the same load limit.
Q: How do I install the PIR motion sensor switch?
A: Installation is straightforward with the plug-and-play link terminal design. Simply connect the wires according to the wiring diagram shown in the product images, then either embed the unit into a ⌀20 mm mounting hole or surface-mount it. No specialist electrician tools are needed, though always ensure power is off before wiring.
Q: What is the recommended mounting height and sensing distance?
A: For optimal performance, mount the sensor at a height of at least 3.5 m. The best sensing distance is 3–5 m, with a maximum detection range of up to 6 m and a 120° wide-angle detection field.
