10PCS Digital Light Intensity Sensor Module Photo Resistor Photoresistor US

Description

Features:
This module is sensitive to the light, Usually used for detecting the ambient brightness and light intensity.
When there is no light or the light intensity can not reach the value, DO output is
high level. when light intensity over than the value, the module DO output is low level.
The module digital output DO can be directly connected with the
microcontroller,use microcontroller detect high or low level, so that can detect the
environmental light intensity change.
Can use this board digital output DO port drive relay module directly, can use as a
photoelectric switch.
The analog output AO connect with AD module,it can get more precise light
intensity value through the AD converter.
Features:
Comparator chip LM393 ,it is stable.
Can detect the ambient brightness and light intensity
Accuracy adjustable
