Ambient light sensing is a significant part of many applications like automatic street lights, solar panels charging controller, automatic irrigations systems where humidity and ambient light determine if the planet needs to be irrigated or not. We usually use a simple Light Dependent Resistor (LDR) as it changes its resistance with the amount of light falling over it, which gives us an idea about the light intensity in the surrounding. But in some cases, we want to know if the light is beyond certain threshold to trigger certain processes in which case this Photosensitive Light Detection sensor module which gives digital output and whose sensitivity can be adjusted with the onboard potentiometer is a great module to use. It has onboard LM393 comparator IC to convert analog signals coming from lDR to the Digital Signals that can be used to connect with the microcontroller or development board you are using.
LDR Sensor Module Specifications
- Operating Voltage: 3.6V to 5V DC
- Adjustable potentiometer to adjust the sensitivity
- LM393 comparator IC for digital output
- Easy to install thanks to bolt hole provided
- Digital Output
This module require 5V supply to work so connect 5V supply to the VCC pin and connect the Digital Output pin to any GPIO Pin of the microcontroller and read the output with digital read function. It has indicator LEDs too to determine the state of output and power.
