Digital Light Intensity Sensor Module Photo Resistor Photoresistor

http:// m5.img.dxcdn.com/CDDriver/CD/SKU 420031.zip Feature: 1£¬ using the sensitive type photosensitive resistance sensor 2£¬ the comparator output signal clean waveform is good£¬ driving ability£¬ than 15mA. 3£¬ with adjustable potentiometer can adjust the brightness of the light detected 4£¬ working voltage 3.3V-5V 5£¬ the output format: Digital switching output (0 and 1) 6£¬ with bolt holes for easy installation 7£¬ a small board PCB size: 3.2cm x 1.4cm 8£¬ using a wide voltage LM393 comparator Module for use: 1£¬ the photosensitive resistor module most sensitive to ambient light£¬ generally used to detect the brightness of the ambient light£¬ triggering microcontroller or relay modules; 2£¬ the module brightness of ambient light reach the set threshold£¬ DO-side output high when the ambient light level exceeds the set threshold£¬ DO-ended output low; 3£¬ DO output can be directly connected with the microcontroller through the microcontroller to detect high and low£¬ thereby detecting changes in ambient light intensity; 4£¬ DO OUR outputs can directly drive the relay module£¬ which can be composed of a light control switch.
