3.3-5V Input LM393 Light Sensor Module for Arduino Raspberry Pi

• The brightness of surrounding environment and the light intensity can be detected (compare with the photoresistor, directivity is relatively good, can perceive the fixed direction of the light source)
• Sensitivity adjustable the blue digital potentiometer adjustment (Figure)
• Operating voltage 3.3V-5V
• Digital switching outputs (0 and 1)
• With fixed bolt hole for easy installation
• Small board PCB size: 3.2cm * 1.4cm

Instructions

• Photodiode module is most sensitive to the ambient light. It is generally used to detect the brightness of the ambient light intensity.
• If the light intensity of less than a set threshold, DO port outputs a high level, when the light intensity exceeds the set threshold value, the module D0 output is low
• The small board digital output D0 can be connected directly with the microcontroller to detect high and low to detect environmental light intensity change
