LM393 Light Sensor Module 3.3-5V Input Light Sensor for Arduino
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
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 / 1.25" * 0.55"
DO port outputs a high level, when the external environment when the light intensity exceeds the set threshold value, the module D0 output is low
