LM393 Photosensitive LDR Sensor Module With Digital Output - 3 Pin

The LM393 Photosensitive LDR Sensor Module is a light detection module that uses an LDR (Light Dependent Resistor) to sense ambient light levels. It features an LM393 voltage comparator to provide a stable digital output signal when the light intensity crosses a set threshold. The module includes an onboard potentiometer for adjusting light sensitivity. It has a DO (digital output) pin that goes LOW when the light level is below the set point. Ideal for DIY electronics, robotics, and smart lighting projects. Operates on 3.3V–5V, making it compatible with Arduino and other microcontrollers.
