This LDR Light Sensor Module uses a photoresistor (light-dependent resistor) to measure light intensity and detect the presence or absence of light. It provides both digital and analog outputs, making it extremely easy to build light-triggered projects.
Key Features:
- Dual Signal Output: Features both Digital Output (DO) for direct switching/threshold triggering and Analog Output (AO) for precise light level measurements.
- Adjustable Sensitivity: Built-in blue potentiometer allows you to easily set the light detection threshold.
- Onboard LED Indicators: Features power indicator LED (PWR-LED) and digital output status LED (DO-LED) for real-time monitoring.
- Easy Microcontroller Connection: Standard 4-pin interface (VCC, GND, DO, AO) connects directly to Arduino, Raspberry Pi, ESP32, and other microcontrollers.
- Versatile Applications: Ideal for automatic night lights, solar light controllers, light-level monitoring systems, and smart home automation projects.
