Abstract

A precised and accurate measurement of environmental pollutants is not always an easy task if we are in presence of variable quantities depending on the process under test. The signal conditioning of sensors dedicated to environmental monitoring is an aspect that strongly impacts on the quality of post processing. The paper presents a design of conditioning circuit for a pyrosensor of carbon oxide emitted by industrial and human activities. The conditioning circuit can be also used for home pollution monitoring in the context of heating and it can be useful for automotive applications too. The conditioning circuit automatically allows the detection of necessary level of pollution in order to produce an alarm to be deployed and/or relay to be acted.
