24GHz Radar Human Presence Sensor Switch – Auto On/Off
Smart Radar Presence Sensor Switch – Auto Lighting Control
Upgrade your home or commercial lighting with this 24GHz Radar Human Presence Sensor Switch. Featuring advanced millimeter-wave radar technology, it detects human presence, movement, breathing, and subtle micro-motions — automatically turning lights on when someone enters and off when the space is empty. The built-in light-sensitive control ensures the sensor only activates in darker environments, preventing unnecessary switching during daylight hours. Made in Mainland China.
Key Features
- 24GHz Radar Presence Detection: Accurately senses human presence, movement, breathing, and small motions indoors — no more fumbling for a switch in dark hallways.
- Light-Sensitive Control: Keeps lights off in bright conditions and enables automatic sensing only when ambient light is low, saving energy effortlessly.
- Wide Lamp Compatibility: Works with LED lamps, energy-saving bulbs, white lamps, ceiling lights, light strips, floor lamps, desk lamps, and other indoor lighting within the 100W rated load.
- Easy 4-Wire Installation: Two-in two-out four-wire wiring design combined with a transparent PC shell lets you observe the wiring process clearly for hassle-free setup.
- Versatile Indoor Use: Ideal for corridors, stairways, entrances, garages, warehouses, bathrooms, and any space that benefits from automatic, hands-free lighting control.
- Energy Saving: 20-second delay timer ensures lights stay on while the space is occupied and switch off promptly when it's not, reducing unnecessary energy consumption.

Frequently Asked Questions
Q: What type of lamps is this radar presence sensor switch compatible with?
A: This sensor switch is compatible with a wide range of indoor lighting including LED lamps, energy-saving bulbs, white lamps, ceiling lights, light strips, floor lamps, and desk lamps — as long as the total load does not exceed 100W.
Q: Will the sensor switch turn on the lights during the daytime?
A: No. The built-in light-sensitive control prevents the sensor from triggering the lights when the ambient environment is already bright. It only activates the lighting in darker conditions, making it both smart and energy-efficient.
Q: How far can the radar sensor detect human presence?
A: The 24GHz radar sensor has a detection radius of 3.5 meters (approximately 11.5 feet), giving a full detection diameter of 7 meters (about 23 feet), making it effective for corridors, bathrooms, garages, and entranceways.
Q: Is this sensor switch easy to install?
A: Yes. The two-in two-out four-wire design is straightforward, and the transparent PC shell allows you to visually verify connections during installation. The mounting hole distance is 60mm, fitting standard switch boxes.
