module instructions
1 photosensitive resistor module is most sensitive to ambient light generally used to detect the brightness of the surrounding environment trigger microcontroller or relay module and the like;
2 when the ambient light level module reach the set threshold value the DO output high when the ambient light level exceeds a set threshold value the DO terminal output low;
3 may be associated with the DO output of the microcontroller Directly connected through the MCU to detect high and low level thereby detecting the change of the light brightness of the environment;
4 DO output can directly drive the store relay module which can form a light control switch.
5 the small board analog output AO can be connected with the AD module through the AD conversion you can get more accurate values of ambient light intensity;
Product wiring instructions:
1 VCC connected to the power supply positive 3.3-5V
2 GND connected to the negative power supply
3 DO TTL switch signal output
