Appearance feature
Initialization
For the initial 20S interval once our motion sensor is powered,our motion sensor’s sensing function is disabled and can’t response to human motion.After that,our motion sensor can work normally and its indication light can be turned on or off by our MH10 remote control.
Factory setting
Detection sensitivity: 100%, Hold time: 1 Minute
Motion signal description
Our 24GHz millimeter motion sensor can precisely detect human movement motion and human presence signal to output presence and absence status,and below is human movement motion and human presence signal description
Remark: Only when our motion sensor is triggered by movement motion firstly,so that it can detect human presence
