Capteur IR NPN

TRANSISTORS - Autoshop 101

The NPN transistor has an emitter made from N-type material. Its base is P-type material and the collector is N-type material. For the NPN transistor to operate, the emitter must be connected to negative, the base to positive and the collector to positive Aside from the way in which the NPN and PNP transistors are connected in the circa they ...

Nondispersive infrared sensor - Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is non-dispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.
