Description

Purpose:
Light intensity detection, the light brightness sensor, intelligent car light module

Module features:
1, using photosensitive resistance sensor sensitive type
2, the comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma.
3, with adjustable potentiometer to adjust light brightness
4, has a fixed bolt hole, convenient installation

Module instructions
1, photosensitive resistance module's most sensitive to ambient light, commonly used to detect environment around the brightness of the light, or MCU trigger relay module, etc.;
2, module in the environment light intensity than set threshold, output high level DO end, when the environment light intensity more than set threshold, the DO output low level;
3, the DO output can be directly connected to microcontroller, through single chip microcomputer to detect the high and low level, thus to detect the environment light intensity change;
4, the DO output can be directly driven our relay module, which can form a light-operated switch.
