10PCS Photodiode Module Detects Brightness Light-Sensitive Light Detector Photosensitive Sensor Module Smart Car for Arduino

Purpose: Detecting light intensity, light intensity sensor, directional, only the inductive sensor in front of the light source for the light to find better Module Features: 1 can detect the brightness and ambient light intensity (compared with the light-sensitive resistors, the direction is good, it can perceive light fixed direction) 2 adjustable sensitivity (blue digital potentiometer adjustment) 3 Operating voltage 3.3V-5V 4 digital switching outputs (0 and 1) 5 has a fixed bolt hole for easy installation 6 small plates PCB size: 3.2cm * 1.4cm Instructions A photodiode modules most sensitive to ambient light intensity, generally used to detect ambient brightness and light intensity, can be common with photosensitive resistance sensor module in most cases, the difference between the two is that the photodiode module better direction, can be perceived a light source fixed direction. 2 module in matt conditions or light intensity does not reach the threshold value, DO port outputs high when the ambient light intensity exceeds a set threshold, the module D0 output low; 3 digital outputs D0 small plates can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the light intensity changes in the environment; 4 small board digital output DO OUR relay module can directly drive, which can be composed of a photoelectric switch;
