Phototransistors

A Phototransistor is a two-lead or three-lead semiconductor that is more sensitive than a photodiode. It senses light levels and uses them to alter currents to create an electrical signal.

The bipolar semiconductor is can be made from silicon or another semi-conductive material.

How do Phototransistors work?

Once detection of light such as IR (infrared), visible light or UV (U...
