conditions such as ambient temperature, wind speed and direction,
relative humidity, etc. can also be recorded as an aid to tracking the
source of the pollution. For example, with AirQ a live "on-screen"
pollution rose can readily be created which plots measurements
against wind heading on a polar chart.
Networked Environmental Monitoring
Creating a network of sensors has never been easier. Any number of sensors can be connected
to an AirQ network created with any combination of fixed wiring (up to 10 km), licence free radio
telemetry (up to 20 km), telephone and GSM cellular modems. A unique feature of the network
is that as each new sensor is connected it automatically informs the PC of what it is designed to
measure, what its engineering units are, what remote control features are available and so on. In
