- Light Detection: Detects ambient brightness and light intensity.
- Adjustable Sensitivity: Sensitivity can be adjusted via the blue digital potentiometer.
- Wide Voltage Range: Operates within 3.3V to 5V voltage range.
- Digital Output: Provides digital switching outputs (0 and 1) via the D0 pin.
Description:
The LDR Light Sensor Module is designed to detect the intensity of light in the surrounding environment. The module’s output goes high when light is present and low when no light is detected. The sensitivity of the detection can be fine-tuned via a digital potentiometer. It features a LM393 comparator chip, ensuring stable operation. The module also provides digital output (0 or 1) which can be connected directly to microcontrollers or relay modules for further automation.
