Grayscale sensor is a sensor module that measures light intensity in grayscale from white (brightest) to black (darkest). The gray sensor module has a photoresistor and a white LED on the board. The grayscale sensor is commonly used in automatic lamps that turn on after dusk. The light sensor module allows you to easily detect light levels from the Arduino controller.
