4pin Optical Sensitive Resistance Light Detection Photosensitive Sensor Module Geekcreit for Arduino

a
Specification: 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 the 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 by our relay module, which can form a light-operated switch. Feature: 1. Using a 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; Package includes: 1 x Photosensitive Sensor Module
