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 : 

• Can detect the brightness and the ambient light intensity (compared with photo-resistor, this module has better directionality , can sense light in fixed direction) 

• Adjustable sensitivity (use the blue digital potentiometer to adjust) 

• Operating Voltage: 3.3V-5V 

• Output Format : DO digital switching outputs (0 and 1) and AO analog voltage output 

• Has a fixed bolt holes for easy installation 

• PCB Size : 3.2cm * 1.4cm 

Module Instructions: 

• 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; 

• 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; 

• 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; 

• Analog output and the AD conversion process, can achieve higher accuracy. 

Product Wiring Instructions: 

• VCC  ----  "+"

• GND ----   "-"

• DO    ----  TTL Signal Output 

• AO    ----  Analog Signal Output
