Description

Digital LDR module

The Digital LDR Module is used to detect the presence of light / measuring the intensity of light. The output of the module goes high in the presence of light and it becomes low in the absence of light. The sensitivity of signal detection can be adjusted using the potentiometer.

You can adjust the threshold (sensitivity) of the digital output by tuning the onboard variable resistor (potentiometer). Simple usage as it is the digital output, so you will know the light present and decide what to do with it.

It comes with an M3 mounting hole for ease of attaching it to an object. Onboard, it provides an LDR, high sensitivity and commonly being used for light detection. The module comes with a power LED and a status LED as an indicator.

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

 

WORKING PRINCIPLE :

  • 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 detects 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.

PIN DETAILS :

  • VCC –  3.3V to 5V DC.
  • GND –  Ground.
  • DO –  Digital Output.

FEATURES :

  • LM393 based design.
  • It can detect ambient brightness and light intensity.
  • Adjustable sensitivity (via blue digital potentiometer adjustment).
  • Output Digital – 0V to 5V, Adjustable trigger level from preset.
  • LEDs indicating output and power.

APPLICATIONS :

  • Automatic Street Light Circuit
  • Simple Fire Alarm Circuit
  • Light Activated Switch Circuit
  • Automatic LED Emergency Light
  • Night Security Light
  • Light Following Robot.
