LDR Photoresistor Sensor Module Description

• photoresistor module most sensitive to ambient light, generally used to detect the brightness of ambient light, triggers microcontroller or relay modules and so on;
• when the ambient light module brightness of less than the set threshold, DO-side output high, when the external ambient light brightness exceeds a set threshold, DO terminal output low;
• DO output can be with the microcontroller directly connected, through the microcontroller to detect high and low, thereby detecting the light intensity changes in the environment;
• DO outputs can directly drive a relay module shop, which can form a light control switch.
• small plates can be connected to analog output AO and AD module, through AD conversion, you can get a more accurate ambient light intensity value;
