C.J. SHOP 5PCS LM393 Light Detection Optical Sensitive Resistance Sensor Module Photosensitive Sensor for Arduino 3 pin

Features:1. The sensitive type photosensitive resistance sensor2. Comparator output, signal clean, waveform, driving ability, more than 15 ma.3. With adjustable potentiometer adjustable testing light brightness4. Working voltage of 3.3 V - 5 V5. Output form: digital switch output (0 and 1)6. With fixed bolt hole, convenient installation7. Small board PCB size: 3.2cm x 1.4cm8. Use of wide voltage LM393 comparator Module instructions:1. Photosensitive resistance module to the ambient light the most sensitive, generally used to detect surrounding environment of the brightness of the light, trigger SCM or relay module, etc.;2. Module in ambient light brightness can not reach the setting threshold, DO end output high level, when external environment light brightness than setting threshold value, DO end output low level;3. DO output port can be directly connected with the single chip microcomputer, through the single chip microcomputer to detect high and low level, thus to testing environment light intensity change;4. DO output end can directly drive the relay module, which can form a light-operated switch. Package Included: 5x LM393 Optical Sensitive Resistance Sensor Module
