use:

Light brightness detection, light brightness sensor, with directionality, only the light source in front of the sensor is sensed, for better light-seeking effect

Module Features:

1 Can detect the brightness and light intensity of the surrounding environment (compared with photoresistors, the directionality is better, and the light source in a fixed direction can be sensed)

2 The sensitivity is adjustable (adjusted by the blue digital potentiometer in the picture)

3 Working voltage 3.3V-5V

4 Output form: DO digital switch output (0 and 1) and AO analog voltage output

5 With fixing bolt holes for easy installation

6 Small board PCB size: 3.2cm * 1.4cm

Instructions for use

1 The photodiode module is sensitive to the ambient light intensity, and is generally used to detect the brightness and light intensity of the surrounding environment. It can be used with the photoresistor sensor module in most occasions. directional light source.

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, and 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 with the single-chip microcomputer, and the high and low levels are detected by the single-chip microcomputer, thereby detecting the change of the light intensity of the environment;

4 The digital output DO of the small board can directly drive the relay module of our store, thus forming a photoelectric switch;

5. The analog output AO of the small board can be connected to the AD module of our store. Through AD conversion, a higher value of the ambient light intensity can be obtained.
