Description:
2-way light detection, brightness detection, by detecting the brightness potentiometer adjustable valve point, comes the relay, do all kinds of brightness detection switch, but also do two sensors sensing, triggering two conditions, the output of the series (and door), two conditions are either triggered, the output of the parallel (or gate), two independent control of three control methods, directly connected with AC power products. (Compare with photoresistor, directional better, you can perceive light fixed direction in front of the photodiode to detect light, it is difficult to detect peripheral)
Module features:
1.using the intensity of the light sensing photodiode sensor, comes with a relay, direct load control
2. Distribution bit adjust sensitivity by adjusting potentiometer setting start relay threshold, when lit this threshold, the module relay close, when the dark this threshold, the relay is released, the relay switch.
3.the working voltage: 12VDC
