3. Product Function

The product adopts a mechanism to report human body status information (unmanned/occupied: walk mode, leisure mode, presence mode) and the light level in every 30 seconds through the MCU serial port.

MSA050 Z1 Breathing Detecting Occupancy Sensor Daylight Accurately 1

Walk Mode: a large movement (walking) of the human body is detected within 30S.

Leisure Mode: only small motion of the human body are detected within 30S, such as: forward, backward, limb

swing, head shaking, typing, playing with mobile phones and other minor actions.

Presence Mode: only detects human breathing within 30S (abdominal cavity, thoracic cavity expansion behavior

actions), no significant movement is detected.

Light Level Report: report the current light level when the light level changes in the preset range.


  1)Sensitivity, indicator light, and hold time function are set through the Tuya APP.

  2)The motion sensor doesn’t work when the sensitivity is set to 0%.

  3)Human occupancy detecting function for switch and automation.

  4)Motion, minor movement, and breathing signals are separated to realize different behavior control mode.

  5)Support the networking function of the master and slave controllers.

  6)Triggered status display (unmanned / occupied:walk mode, leisure mode, presence mode).
