Abstract

This paper describes a metal oxide nano gas sensor for environmental monitoring subsystem in real time, this gas sensor with a semiconductor type microelectromechanical system (MEMS) which consumes low power and is highly responsive made for environmental monitoring applications. This subsystem was developed using a gas sensor module, a Bluetooth module, and a personal digital assistant (PDA) telephone. The gas sensor module consists of a NO2 or CO gas sensor and a signal processing chip. The MEMS gas sensor consists of a micro heater, a sensing electrode, and a sensing material. Metal oxide nano powder is coated onto the substrate using a microheater and integrated into the gas sensor module. The change in resistance of metal oxide nano powders from exposure to oxidizing or deoxidizing gases is used as the principle mechanism of operation of this gas sensor. The variations detected in the gas sensor module are transferred to the PDA phone via the Bluetooth module. The results of this study indicate an air quality monitoring system to monitor carbon monoxide and nitrogen dioxide gas parameters.
