Uses:
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:
- Can detect the brightness of surrounding environment and the light intensity (with a photoresistor comparison, good directivity, can perceive the fixed direction of the light source)
- Adjustable sensitivity adjust the digital potentiometer (shown in blue)
- Operating voltage 3.3V-5V
- Digital switch outputs (0 and 1)
- Has a fixed bolt hole for easy installation
- Small plates PCB size: 3.2cm * 1.4cm
Instructions for use:
- 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 be perceived the fixed direction of the light source.
- 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;
- Small plates digital outputs D0 can be directly connected with the microcontroller, microcontroller to detect high and low, and to detect environmental light intensity change;
- Small plates DO digital output can directly drive the shop relay module, which can be composed of a photoelectric switch
