Product Description

         This LM393 Photosensitive Light-Dependent Control Sensor LDR Module is using a high-quality LM393 voltage comparator. Easy to install using the sensitive type photosensitive resistance sensor the comparator output signal gives a clean and good waveform.

         Driving ability is 15mA with the adjustable potentiometer, it can adjust the brightness of the light. Working voltage is 3. 3V to 5v. Where output is a digital switch output. Since this module is sensitive to the light, usually used for detecting the ambient brightness and light intensity.
