LM393 Light Sensor Module 3Pin 3.3V 5V Photosensitive Diode Sensor Detection Module with Digital Analog Output for Arduino
Usage:




Light level detection, the brightness of the light sensor is directional, only inductive sensor in front of the light source used to find light better



Module Features:



1. The brightness of surrounding environment and the light intensity can be detected (compare with the photoresistor, directivity is relatively good, can perceive the fixed direction of the light source)
2.Sensitivity adjustable the blue digital potentiometer adjustment (Figure)
3. Operating voltage 3.3V-5V
4. Digital switching outputs (0 and 1)
5. With fixed bolt hole for easy installation
6. Small board PCB size: 3.2cm * 1.4cm / 1.25" * 0.55"



Instructions for use:



1. Photodiode module is most sensitive to the ambient light, generally used to detect the brightness of the ambient light intensity, photoresistor sensor module Universal In most cases, the difference between the two is that photodiode module directional, can sense the fixed the direction of the light source
2. Module in the light conditions or the light intensity of less than a set threshold, DO port outputs a high level, when the external environment when the light intensity exceeds the set threshold value, the module D0 output is low
3. The small board digital output D0 can be connected directly with the microcontroller microcontroller to detect high and low to detect environmental light intensity change
4. Small board digital output DO OUR relay module can directly drive, which can be composed of a photoelectric switch

Module instructions

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.
