20pcs 4pin Optical Sensitive Resistance Light Detection Photosensitive Sensor Module Geekcreit for Arduino - products th

Specification 1 Photosensitive resistance modules 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 lightintensity 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 lowlevel 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 20 x Photosensitive Sensor Module
