2-channel relay module 12v remote control mudule combined photosensitive sensor module light detection odiode module 2-channel relay module 12v relay module combined photosensitive sensor module light detection
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,
4. Output Type: AC 220V 10A directly connected or DC30V 10A load
5 with 4 fixing bolt holes for easy installation
6, a small PCB board size: 6.3cm x 4cm
7, using a wide voltage comparator LM393
Module for use:
A photosensitive module most sensitive to ambient light, generally used to detect the brightness of ambient light (compared with photoresistor, directional better, you can perceive light fixed direction in front of the photodiode to detect light, surrounding difficult to detect often should look for light function).
2, when the module is in the ambient light exceeds a set threshold, the relay is turned on at the beginning,, when the ambient light is below the set threshold, the relay off, relay switch off;
Package:
1X 2CH photosensitive relay
