Features:
Application: Light brightness detection, light brightness sensor, smart car light seeking module.
The module adopts high sensitivity photoresistor sensor for quick response.
Using wide voltage LM393 comparator output, stable signal, clean signal, strong driving ability.
Adjustable light brightness detection sensitivity by potentiometer.
Working voltage 3.3V-5V,  with fixed bolt holes for easy installation.
Output form: digital switching value output (0 and 1).
 

Specification:
Operating voltage: 3.3V-5V
PCB size: 32*14cm / 1.26*0.55in
 
Module Instructions:
1. The photoresistor module is most sensitive to ambient light and is generally used to detect environment around the brightness of the light, triggering a microcontroller or relay module, etc.
2. When ambient light intensity does not reach the threshold value, the module DO port output high. When the ambient light level exceeds the set threshold, the DO output is low.
3. The DO output can be directly connected to the microcontroller, and the high and low levels can be detected by the MCU, thereby detecting the light intensity changes in the environment.
4. The small-plate analog output AO can be connected to the AD module. Through AD conversion, a more accurate value of the ambient light intensity can be obtained.
