4. Wiring
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 in a line, you shall consider that all equipment current consumption shall not surpass your driver’s loading capacity.
5. Detection
6. Initialization
When powered on, the sensor indicator will turn off after flashing for 10 seconds and will enter a 20S detection cycle. If presence is detected, the sensor will report presence and enter hold time calculation; if absence is detected,then the sensor will report absence. During initialization, the sensor will not detect a moving signal, and you can use our MH18 remote to adjust detection area,hold time, daylight sensor, etc, parameters.
