light sensor module(LDR)

Module Features:
1, the use of sensitive photoresistor type sensor
2, the comparator output signals clean, good waveform, driving ability, than 15mA.
3 with adjustable potentiometer to adjust the brightness of the light detected
4, the working voltage of 3.3V-5V
5, the output form: digital switching output (0 and 1)
6, a fixed bolt hole for easy installation
7, small PCB board size: 3.2cm x 1.4cm
8, using a wide voltage comparator LM393
Module Description
1, ambient light module photoresistor most sensitive, generally used to detect the brightness of ambient light, single-chip trigger or relay module;
2, the module when the ambient light brightness of less than the threshold value, DO-side output high, when the ambient light level exceeds the set threshold, DO terminal output low;
3, 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;
4, DO output of the relay module can directly drive the shop, which can be composed of a light control switch.
