Phototransistor
A transistor that has a light-sensitive base region
A phototransistor is more sensitive than a photodiode. A common type of phototransistor is a bipolar transistor housed in a transparent casing so that the base-collector junction can sense the light. Phototransistors are used to convert light signals into amplified electrical signals. Like all the optical sensors you can access using our site, these devices are built to last by go-to manufacturers like Honeywell and Osram Opto.
