  • 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
