The first is the … NettetUn fototransistor es un elemento electrónico que se basa en la luz como el mecanismo de control de compuerta y regulador de corriente. La mayoría de los fototransistores se fabrican con forma de un transistor bipolar, lo que significa que se utiliza una estructura de base-colector-emisor. La principal diferencia es que el material ...

NettetDirect DC IR LED emitter to a phototransistor path only works for a short distance (1m) You can increase that with the square root of drive current due to distance inverse square law. If you want a high gain receiver for long distance then you need to modulate in the 30~50KHz range with a matched IR Rx part just like most IR remote controls.

NettetA phototransistor is a light-sensitive transistor. A common type of phototransistor, the bipolar phototransistor, is in essence a bipolar transistor encased in a transparent case so that light can reach the base–collector junction. beaster bunny
