LM393 Photosensitive Light-Dependent Control Sensor LDR Module
This LM393 Photosensitive Light-Dependent Control Sensor LDR Module utilizes a high-quality LM393 voltage comparator. It is easy to install, employing a sensitive photosensitive resistance sensor. The comparator’s output signal provides a clean and well-defined waveform.
With an adjustable potentiometer, the driving ability is 15mA, allowing you to adjust the brightness of the light. The working voltage ranges from 3.3V to 5V, and the output is a digital switch output. Due to its sensitivity to light, this module is commonly used for detecting ambient brightness and light intensity.
You can directly use the digital output (DO) port of this board to drive relay modules (which are available in our store), or you can use it as a photoelectric switch. The analog output (AO) can be connected to an AD module, providing a more precise light intensity value through the AD converter.
