Module for use

Photosensitive resistor module most sensitive to ambient light, generally used to

detect the brightness of ambient light, triggering microcontroller or relay modules;

When the brightness of ambient light module can not reach the set threshold, DO-side

output high when the ambient light level exceeds the set threshold, DO end 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 to change;

DO output of the relay module can directly drive the shop, which can be composed of a

light control switch

Package Included:

1 X Photosensitive resistor module
