Note:

Module operating instructions
1.Photosensitive resistor module most sensitive to ambient light, generally used for testing the brightness of the ambient light, triggering single-chip or relay module;
2, module in the ambient light intensity does not meet threshold value, the DO Terminal output high, when the outside ambient light intensity exceeds the set threshold value, the DO Terminal output low;
3, DO the output can be directly connected to the microcontroller, by single-chip computer to detect high or low level, to detect light intensity changes of the environment;
4, DO the output can directly drive our relay modules, which can form a light control switch.
5, analog output AO and AD module, by AD conversion, light intensity can be obtained more accurate values;
Wiring instructions:
1, the VCC to supply cathode 3.3-5V
2, GND connect the negative pole
3, DO TTL signal output
4, AO analog signal output
