Photosensitive Resistor Sensor Module for Arduino

Description

1. Light Sensing: The module uses a photosensitive resistor (LDR) to detect changes in ambient light levels. The resistance of the LDR varies with light intensity.
2. Analog or Digital Output: Depending on the module, it may provide either an analog voltage signal (proportional to light intensity) or a digital signal (HIGH/LOW) when a certain light threshold is reached.
3. Adjustable Sensitivity: Some versions of the module have a potentiometer for sensitivity adjustment, allowing you to set the threshold for digital output.
4. Compact Size: These modules are typically small and easy to integrate into your Arduino-based projects.
5. Low Power Consumption: They are designed to be energy-efficient and can be used in battery-powered applications.
