LDR Digital Light Intensity Detection Photosensitive Sensor

Application: 

Light intensity detection, intelligent car light module, with directional, only sense light source in front of the sensor, better to use for searching light. 

Module 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 

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.
