LM393 Photosensitive LDR Light-Dependent Control Sensor Module

The LM393 Photosensitive LDR Light Sensor Module 4 Pin helps detect light and control brightness. It uses an LM393 voltage comparator, which gives a clear output signal. You can adjust the light sensitivity with a small dial, making it easy to use for different brightness levels. This module works with a 3.3V to 5V power supply and gives a digital output, making it perfect for detecting light levels around it. It can directly control relay modules or act as a light-activated switch for various projects.
