The PIR Motion Sensor Light Switch with Adjustable Lux Housing is designed with a high-sensitivity infrared detector and integrated circuit technology. It combines automation, safety, energy saving, and convenience in one compact device.

This sensor uses infrared energy from the human body as the control signal source. When a person enters the detection area, the sensor automatically activates the connected lighting load. It can automatically distinguish between day and night, ensuring efficient lighting control while reducing unnecessary power consumption.

The sensor is easy to install and widely used in residential, commercial, and industrial environments such as corridors, stairways, garages, warehouses, offices, and entrances.

With adjustable detection distance, time delay, and ambient light sensitivity (Lux), the PIR motion sensor provides flexible control and reliable performance for automatic lighting systems.

Key Features

• Automatic Motion Detection – Detects human movement using infrared technology and automatically switches lights on.

• Day & Night Recognition – Adjustable Lux setting allows operation during daytime or only in low light conditions.

• Adjustable Detection Distance – Sensitivity can be adjusted between 3m and 6m depending on installation location.

• Adjustable Time Delay – Lighting delay can be set from 10 seconds to 7 minutes.

• 360° Detection Coverage – Wide detection angle ensures reliable motion sensing.

• Energy Saving Control – Lights operate only when motion is detected, reducing energy consumption.

• Easy Installation – Suitable for ceiling installation with a recommended height of 2.2m – 4m.

• Adjustable Functions

  Day & Night Detection

  The sensor can detect ambient light conditions.

  • When set to “SUN” (maximum), the sensor works both day and night.

  • When set to “MOON” (minimum), the sensor works only when ambient light is below 3 LUX.

  Sensitivity Adjustment

  Detection range can be adjusted according to the installation environment:

  • Low sensitivity: about 3m detection distance

  • High sensitivity: up to 6m detection distance

  Time Delay Function

  The delay time resets when additional motion is detected during operation, ensuring continuous lighting when movement persists.
