Digital LDR Module Sensor

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