Module instructions：
1. Photosensitive resistance module to the ambient light the most sensitive, generally used to detect surrounding environment of the brightness of the light, trigger SCM or relay module, etc.;
2. Module in ambient light brightness can not reach the setting threshold, DO end output high level, when external environment light brightness than setting threshold value, DO end output low level;
3. DO output port can be directly connected with the single chip microcomputer, through the single chip microcomputer to detect high and low level, thus to testing environment light intensity change;
4. DO output end can directly drive the relay module, which can form a light-operated switch.
1. VCC positive power supply 3.3-5V
2. GND power supply is negative
3. DO TTL switching signal output
