Module Instructions:
1.Photodiode module is most sensitive to environmental light intensity , generally used for detecting the ambient brightness and light intensity , can be common with photosensitive resistance sensor module in most cases , the difference between this two is that Photodiode module has a better directionality, can sense light in fixed direction;
2. When ambient light intensity does not reach the threshold value, the module DO port output high; when the ambient light intensity exceeds a set threshold, the D0 output low;
3.Digital outputs D0 can be directly connected with the microcontroller through the microcontroller to detect high and low , thereby detecting the light intensity changes in the environment;
4. Analog output and the AD conversion process, can achieve higher accuracy.
Features :
1.Can detect the brightness and the ambient light intensity (compared with photo-resistor, this module has better directionality , can sense light in fixed direction)
2.Adjustable sensitivity (use the blue digital potentiometer to adjust)
3.Operating Voltage: 3.3V-5V
4.Output Format : DO digital switching outputs (0 and 1) and AO analog voltage output
5.Has a fixed bolt holes for easy installation
6.PCB Size : 3.2cm * 1.4cm
