Description

LM393 Photosensitive Light-Dependent Control Sensor

The LDR Sensor Module detects the presence and intensity of light, making it ideal for projects requiring light measurement. The module outputs a high signal in bright conditions and a low signal in the dark. Sensitivity is adjustable via a potentiometer, allowing precise control based on your needs.
