Photoresistor Light Sensor Module for Arduino
A photoresistor is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in light-sensitive detector circuits, and light-activated and dark-activated switching circuits
A photoresistor module makes it easy to use on breadboards and Arduino projects
