SMOG

Pollution detection made faster and easier

Early detection of pollution is becoming more important, as society recognises the damage that pollution causes. Unfortunately, existing pollution detection instruments tend to be bulky and not easily transportable.

The SMOG project aims to make early pollution detection more feasible by developing miniaturised silicon-integrated metal-oxide gas sensors. Such sensors give a drastic reduction in the volume and power consumption of an air quality monitoring station. Target gases for measurement can be selected using the latest pattern recognition techniques.

The project has achieved a number of key developments. These include low power consumption substrate heater elements for thin film sensors and a miniaturised metal-oxide, thin film gas sensor integrated into a system of actuator components. In addition there is a miniaturised gas chromatographic subsystem, for the measurement of solvents, and advanced techniques for sensor control, signal conditioning and pattern recognition. The end result is a miniaturised gas monitoring station. This has small dimensions, reduced power consumption, self-calibration and testing of sensor units.

The long operational periods and low cost of SMOG instruments makes them especially attractive for anyone wishing to install monitoring networks. The high sensitivity to ozone also makes the sensors suitable for new applications in indoor air quality monitoring.

A miniaturised air quality monitoring station is on the SMOG stand. It is capable of detecting a range of important air pollutants produced by road traffic.
