Návrh a realizace snímače toxických plynů s komunikací prostřednictvím protokolu FINET

Abstract

This diploma work deals with the measurement of two toxic gases and this methane (CH4) and carbon monoxide (CO) by a sensor TGS3870. After measuring the concentration of the gases in the atmosphere, the data stored in the microprocessor memory and on request of the master device are sent to the device. The communication protocol is FINET. Part of the work is physically tangible and functional prototype. The prototype is intended for indicative measurements, but hardware is designed to be universal and provides many possibilities extension functions.
