Product Description
Product Description
The LM393 Photosensitive LDR Light-Dependent Control Sensor Module is designed to detect ambient light levels and provide a digital output based on light intensity. It uses a Light Dependent Resistor (LDR) along with the LM393 comparator chip to compare light levels against a user-defined threshold.
The module features an adjustable potentiometer, allowing easy control of sensitivity for different lighting conditions. When the light intensity crosses the set level, the output changes accordingly, making it ideal for automatic lighting systems, day-night detection, robotics, and Arduino-based projects.
