An IR sensor is basically a device which consists of a pair of an IR LED and a photodiode which are collectively called a photocoupler or an optocoupler. The IR LED emits IR radiation. The IR radiation is emitted in a beam from the IR LED. When this beam is disturbed, it widens and "hits" the photodiode. The photodiode converts the IR light into an electrical current. Because the output of ...

· As an integral aspect of the transistor’s defining equations, the temperature sensitivity of the PN junction is quite predictable and very linear over the typical semiconductor operating range of 55 to +150°C. In addition to a PN junction in a diode, a semiconductor junction temperature sensor can be achieved by short circuiting the collectorbase junction of a bipolar transistor to create ...

· Habe ne Frage wie man aus einer Infrarotdiode und einem Fototransistor einen Abstandssensor baut. Also die IRDiode soll gegen das Hindernis strahlen, welches die Strahlen reflektiert. Diese werden von dem Fototransistor aufgenommen und dieser schaltet durch. Das ganze soll an einen ATMega8 angeschlossen werden zum Regeln eines Fahrzeuges.
Bei der IRLED muss man diese gegen das Licht halten, da ansonsten der Aufbau nur schwer erkennbar ist. Beim Transistor fällt sofort auf, dass dieser nur 2 Anschlüsse besitzt. Der dritte Anschluss, die Basis, fehlt hier. Die Basis wird durch das einfallende IRLicht ersetzt. Je nach Lichtstärke, steuert der Transistor mehr oder weniger durch.

· An IR proximity sensor is a device which detects the presence of an object or a human when it is within a predetermined range from the sensor, through reflected infrared beams. Three useful proximity sensor concepts are explained here, the first concept is based on an ordinary opamp LM358, the second one using IC LM567 which functions with a phase locked loop principle ensuring very …

An infrared (IR) phototransistor is a transistor that can only trigger on with infrared light. How a phototransistor works is it has 2 terminals, an emitter and collector. It does not have a terminal connection to its base. The base is simply made up of infrared lightsensitive material.
