Description:
The LM393 Photosensitive LDR Sensor Module! This versatile light detection module uses an LDR (Light Dependent Resistor) to accurately sense ambient light levels.
At its core, an LM393 voltage comparator ensures a stable digital output signal. You can easily set your desired light intensity threshold using the onboard potentiometer, giving you precise control. When the light level drops below your set point, the DO (digital output) pin conveniently goes LOW, triggering your desired action.
Operating seamlessly on 3.3V–5V, this module is fully compatible with Arduino and other popular microcontrollers, making integration a breeze. It's an ideal choice for a wide range of applications, including DIY electronics, robotics, and smart lighting systems.
