Module instructions:

• The photoresistor module is most sensitive to ambient light and is generally used to detect the brightness of ambient light, triggering a microcontroller or relay module, etc.
• When the brightness of the ambient light reaches the set threshold, the DO end outputs a high level, and when the ambient light brightness exceeds the set threshold, the DO end outputs a low level;
• The DO output terminal can be directly connected to the single chip microcomputer, and the high and low levels are detected by the single chip microcomputer, thereby detecting the change of the light brightness of the environment;
• The DO output can directly drive the relay module of the store, which can form a light control switch.

Product wiring instructions:

• VCC is connected to the positive pole of the power supply 3.3-5V
• GND is connected to the negative pole of the power supply
• DO TTL switch signal output

Shipping list:
