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.
Capteur de flamme. Le capteur de flamme peut être utilisé pour détecter une source d'incendie ou d'autres sources lumineuses de longueur d'onde comprise entre 760 nm et 1100 nm. Il est basé sur le capteur YG1006 qui est un phototransistor au silicium NPN à haute vitesse et très sensible.

Dec 23, 2013· La solution NPN offre une immunité beaucoup moins bonne aux parasites présent dans le fil de liaison de 0V entre le capteur et l'interface. Rajoute un générateur de bruit en série avec ce fil de 10V crête/crête et regarde le résultat avec la solution NPN et la solution PNP . J'aime pas le Grec. 23/12/2013, 17h49 #28. ibtihel.
Mar 24, 2019· IR Proximity Sensor simulation in Proteus: Now let us discuss the simulation of the Proximity sensor in the Proteus. It is important here to mention that in order to simulate the behavior of any circuit in any software it is important that the simulation models of all of the components that are used in the circuit should be present in the library of the software.
SICK has a wide range of optic and ultrasonic solutions that measure from sub-microns to kilometers. They solve measuring, detecting and positioning applications using triangulation and time-of-flight modes. Sensors using triangulation are ideal for short-range, highly precise measurement. They can inspect miniature parts, thickness and shape, etc. Time-of-flight sensors work at longer ...

Jul 12, 2019· NPN devices are known as “Sinking” and can switch the negative side. An NPN device “sinks” or provides -24 V to the input card when active. Also, the terms Sourcing and Sinking alone are not enough to describe the configuration because SINKING provides a path to ground and SOURCING provides a path to V+.
