    • Photosensitive resistor module most sensitive to environmental light intensity is generally used to detect the ambient brightness and light intensity.

    • Module light conditions or light intensity reach the set threshold, DO port output high, when the external ambient light intensity exceeds a set threshold, the module D0 output low;

    • Digital output D0 directly connected to the MCU, and detect high or low TTL, thereby detecting ambient light intensity changes;

    • Digital output module DO  can directly drive the relay module, which can be composed of a photoelectric switch;



    Features:

    • Able to detect ambient brightness and light intensity

    • Adjustable sensitivity (via blue digital potentiometer adjustment)

    • Operating voltage 3.3V-5V

    • Digital switching outputs (0 and 1) -D0

    • With fixed bolt hole for easy installation

    • Small board PCB size: 3cm * 1.6cm

    • Power indicator (Red) and the digital switch output indicator (Green)

    • Features wide range voltage comparator LM393

    Pin outs:

    • External 3.3V-5V VCC

    • External GND ground

    • DO digital output interface, a small plate (0 and 1)


      For Light intensity detected,light brightness sensors,Smart car module
      Using the sensitive type photosensitive resistance sensor
      Waveform of the comparator output signal is good,strong driving ability
      With adjustable potentiometer can adjust and detect the brightness of the light
      Come with bolt holes for easy installation

      Specifications:


      Working voltage 3.3V-5V
      the output format: Digital switching output (0 and 1)
      Size:32 x 13 x 7mm(L x W x H)
