 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
