Photodiode Sensor Module, 4 Pins Photodiode Sensor Module, 5mm Photodiode Module, for Digital Light Brightness Detection, Photosensitive Sensor Module for Arduino(10PCS)

Description

Instructions for the use of the photodiode sensor module: 1 The photodiode module is most sensitive to ambient light intensity and is generally used to detect the brightness of the surrounding environment and light intensity, which can be used with the photoresistor sensor module on most occasions. The difference between the two is therefore, that the photodiode module has good directivity and can sense the light source in a fixed direction. 2 When the module has no light conditions or the light intensity does not reach the set threshold, the DO port outputs a high level, When the ambient light intensity exceeds the set threshold, the module D0 outputs a low level; 3 The digital output D0 of the small board can be directly connected to the microcontroller, and the highLow level to detect changes in ambient light intensity; 4 The digital output DO of the small board can directly drive the relay module of our store, which can be composed of a photoelectric switch; 5. The analog output AO of the small board can be connected to the AD module of our store, and through AD conversion, more accurate values of the ambient light intensity can be obtained
