LM393 LDR Module | Light Sensor with Digital and Analog Outputs

Description

The LM393 LDR Module is a high-precision light sensor that can be used to detect the presence and intensity of light. It has both digital and analog outputs, making it versatile for a wide range of applications.

The module uses a high-quality LM393 voltage comparator to digitize the analog signal from the LDR sensor. This ensures a clean and accurate output signal. The module also has an adjustable potentiometer that can be used to set the sensitivity of the digital output.

The digital output of the module can be used to drive a relay module or other device directly. The analog output can be connected to an analog-to-digital converter (ADC) in a microcontroller for more precise light intensity measurement.

Pinout:

• VCC: Power supply pin
• GND: Ground pin
• AO: Analog voltage output proportional to light intensity
• DO: Digital signal output (HIGH or LOW) based on a set threshold light level
