DIYables LDR Light Sensor Module for Arduino, ESP32, ESP8266, Raspberry Pi, 4 pieces

WHERE TO BUY

DESCRIPTION

This package includes 4 pieces of digital light sensor module.

SPECIFICATION

• Digital LDR Photosensitive Light Sensor Module. The triggered threshold is adjustable via a built-in potentiometer
• Two output pins: Digital (LOW / HIGH) and Analog
• Supply voltage: 3.3 - 5V DC
• Digital LDR light sensor for Arduino, ESP32, ESP8266, Raspberry Pi, or any 5V or 3.3V microcontroller.

DO (Digital Output)pin:

The module has a built-in potentiometer that you can turn to adjust the sensitivity of the light detection.

• When the light around the module is brighter than the set threshold, the DO pin of the sensor becomes low, and the LED connected to the DO pin turns on.
• When the light around the module is dimmer than the set threshold, the DO pin of the sensor becomes high, and the LED connected to the DO pin turns off.

AO (Analog Output) pin:

• The value read from the AO pin is lower when the surrounding light is brighter.
• The value read from the AO pin is higher when the surrounding light is dimmer.

Please note that adjusting the potentiometer does not affect the value read from the AO pin.
