LM393 Optical Sensitive Resistance Light Detection Photosensitive Sensor Module for Arduino 4pin DIY Kit

Features

   1 Using photosensitive resistance sensor sensitive type;

   2 Working Voltage:3.5V-5V;

   3 Output form:Digital Switch show (0 and 1);

   4 Fixed Bolt Hole,easy installation;

   5 Small PCB size:3.2CM*1.7CM;

   6 the comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma;

   7 with adjustable potentiometer to adjust light brightness;

Instructions

   1 Photosensitive resistance module's most sensitive to ambient light, commonly used to detect environment around thebrightness 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.
