Light Sensor
[00025]

Light Intensity Sensor:

Module Features:
1, Using photosensitive resistance sensor or (LDR) Light Dependent Sensor.
2, Driving ability, more than 15mA. 
3, With adjustable potentiometer can adjust the light intensity detected.
4, Working voltage 3.3V-5V.
5, Output Type: Digital switching output (0 and 1) and Analog Output. 
6, With bolt holes for easy installation. 
7, Small PCB size : 3.2cm x 1.4cm 
8, Using a wide voltage LM393 comparator.

1, Photoresistor module most sensitive to ambient light, generally used to detect the brightness of the ambient light, triggering microcontroller or relay module; 
2, When the outside ambient light intensity exceeds a set threshold, DO-ended output will be low; 
3, DO output can be directly connected with the microcontroller to detect high and low, thereby detecting ambient light levels change; 
4, the output can directly drive DO OUR relay module, which can be composed of a light control switch.
