Reliably Detecting Human
Presence with High Accuracy

WS202 utilizes a powerful combination of PIR detection and brightness measurement, allowing it to determine an indoor area's occupancy or vacancy status effortlessly.

Smart Brightness Measurement

WS202 allows users to define a custom threshold, enabling it to determine whether a space should be classified as bright or dark.

  • Resolution: 1 lux
  • Range: 1 to 60000 lux
