In this paper a review of different technologies for gas sensors is presented. The different
types of gas sensors technologies including catalytic gas sensor, electrochemical gas …

High demand of semiconductor gas sensor works at low operating temperature to as low as
100° C has led to the fabrication of gas sensor based on TiO2 nanoparticles. A sensing film …

SnO2 has been confirmed to be a potential sensor to many toxic volatile gases. We report
here the synthesis of porous SnO2 nanoflowers by in situ oxidization of SnS and SnS2 …

A simple, cheap, and integrated architecture is introduced to measure gases with a thick film
gas sensor. The temperatures of the sensors are stabilized by controlling the heaters of the …

Fire breakouts or fire accidents are no less than the situation of an armada and it requires
quick recognition and quick resolution which can help us from major barriers of accidents …

La mesure de la qualité de l'air intérieur est un besoin relativement récent. Les êtres
humains passent plus de 90% de leurs temps dans un environnement fermé (pièce …

This paper presents about the development of automated monitoring device for
environmental air pollutant detection. The main part of the device consists of a detector …
