Product details

Product dimension

  • Dimension: φ52.5x34mm
  • Terminal: 4pin terminal

 

Initialization

When powered on,sensor indicator will turn off after flashing for 10S and will enter a 20S detection cycle,if there’s presence detected,then sensor will enter hold time calculating,if absence detected,then sensor relay will disconnect.During initialization,sensor will not detect moving signal and you can use our MH10 remote to adjust detection area、hold time and daylight sensor etc parameter.

 

Factory setting

Detection Area: 4m(medium sensitivity),  Hold Time: 30S,  Daylight Sensor: Disable,  Indicator light: open

 

Detection Signal

The product detects human moving, minor moving, and presence signals, and realizes the detection of human-existing/no-human in non-sleep state. The following is a description of the moving, minor moving and presence signals:

  • Majormovement: detect the human significant moving (walking) in the detection area.
  • Minor movement: detect the human slight moving in the detection area, such as leaning forward, leaning forwarder and back, swinging limbs, shaking head, typing, playing with mobile phones and so on.
  • Micro movement: detect human abdominal and thoracic expansion behaviors caused by breathing, but not detect moving signal and minor moving signal.

Wiring suggestions

 

Wiring layout suggestion:

  1. Hand-in-hand wiring is highly recommended,yet star-topology or tree-topology is strongly deprecated
  2. When there’s more than 1pc sensor is a line,you shall consider all equipment current consumption shall not surpass your driver’s loading capacity.
