1.2.3 Ambient Light Sensor
A phototransistor and bias resistor form a light detection transducer on the Room Sensor. The
light sensor provides a sufficient window of detection to allow detection of desired light levels.
This window will be tuned as necessary by changing the resistor to give a detection window
