DIYables LDR Light Sensor Module for Arduino, ESP32, ESP8266, Raspberry Pi, 4 pieces
Click to zoom
Quick Overview
This 4-piece digital LDR light sensor module set features adjustable threshold sensitivity via built-in potentiometer and dual output modes (digital and analog) for versatile light detection applications. Perfect for automatic lighting control, day/night detection, and ambient light monitoring.
The digital output (DO) provides HIGH/LOW signals based on adjustable threshold, while the analog output (AO) gives continuous light intensity readings. Compatible with 3.3V and 5V microcontrollers.
Key Features
- Dual Output Modes: Digital (HIGH/LOW) and Analog (continuous) outputs
- Adjustable Threshold: Built-in potentiometer for sensitivity adjustment
- 4-Piece Set: Multiple sensors for various projects
- Digital Output (DO): LOW when bright (above threshold), HIGH when dim
- Analog Output (AO): Lower values = brighter light, higher values = dimmer light
- Wide Voltage Range: 3.3-5V DC operation
- LED Indicator: Shows digital output state
