LM393, Light Sensor Module 4Pin 3.3V 5V Photosensitive Diode Sensor Detection Module with Digital Analog Output for Arduino
$42.50
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)
