Module Features: 

• Using the sensitive type photoresistor sensor 
• The comparator outputs a signal clean, good waveform driving ability more than 15mA. 
• With adjustable potentiometer can adjust the light intensity detected 
• The working voltage: 3.3V-5V 
• The output format: Digital switching output (0 and 1) 
• With a fixed bolt holes for easy installation 
• Small PCB board size: 3.2cm x 1.4cm 
• Using a wide woking voltage range LM393 comparator 
• Application: Light intensity is detected, the light intensity sensor, smart car search light module 

Module Instructions 

• Photosensitive resistor module most sensitive to environmental light, generally used to detect the brightness of ambient light, triggering microcontroller or relay module; 
• When ambient light intensity does not reach the threshold value, the module DO-side output high when the ambient light level exceeds the set threshold, DO terminal output low; 
• DO output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the brightness of ambient light changes; 
• DO output can directly drive the relay module, which can be composed of a light control switch. 
• Analog output and AD module, through AD conversion, can obtain more accurate values of ambient light

Product wiring instructions: 

• VCC for positive power supply 3.3-5V 
• GND for power supply is negative 
• DO TTL switching signal output
• AO analogue signal output
