LDR Light Sensor Module for Arduino, ESP32 & IoT Projects – Light Dependent Resistor Module SDTech Robotics

Product Description

The SDTech Robotics LDR Module is a simple and reliable light intensity sensing module that detects changes in ambient light using a Light Dependent Resistor (LDR). The resistance of the LDR varies with light intensity, enabling accurate light detection for automation and control projects.

This module provides both analog and digital output, making it suitable for a wide range of applications such as automatic street lights, smart lighting systems, day/night detection, and energy-saving automation projects. It is easy to interface with Arduino, ESP32, ESP8266, Raspberry Pi (via GPIO/ADC) and other microcontrollers.

Ideal for DIY electronics, robotics, IoT projects, and STEM education.
