1PCS Optical Sensitive Resistance Light Detection Photosensitive Sensor Module for arduino 4pin DIY Kit

  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. 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;    1×Photosensitive Sensor Module
