Product dimension
Initialization
When powered on,sensor indicator will turn off after flashing for 20S and will not detect moving signal during this time. After 20S,you can use tuya APP to adjust detection area and hold time.
Factory setting
Detection Sensitivity: 100%, Hold Time: 5s
Detection Signal
The product detects human moving signals and below is a description of the moving signals:
Remark: we recommend no more than 6pc sensor in a 250mA-circle to avoid communication problem due to insufficient loading problem.
