LDR 5MM LM393 Module – 4 Pin ADC
Compact LDR 5MM LM393 light sensor module with 4-pin ADC and digital output. Ideal for Arduino, IoT, automation, and robotics projects.
Description
The LDR 5MM LM393 Module (4 Pin ADC) is a compact and reliable light-sensing module designed for precise ambient light detection. Built with a 5mm Light Dependent Resistor (LDR) and the LM393 comparator IC, this module converts light intensity into both analog and digital output signals, making it ideal for microcontroller-based projects.
It features an onboard potentiometer for adjustable sensitivity, allowing accurate threshold setting for different lighting conditions. The 4-pin interface ensures easy connection with Arduino, Raspberry Pi, ESP8266/ESP32, PIC, and other development boards.
Perfect for automation, robotics, and IoT applications, this module offers stable performance, low power consumption, and simple integration.
