Analog Ambient Light Sensor

DFRobot's new Analog Ambient Light Sensor. New, improved, design and much more convenient to use. The environmental PT550 light sensor is more sensitive to light. This module helps you detect light density and sends the analog voltage signal back to the Arduino controller. Sensor can also be used as a digital input, setting the detection threshold on the sensor.
