A Low Cost Fully Integrable in a Standard CMOS Technology Portable System for the Assessment of Wind Conditions

Nowadays, the environmental meteorological monitoring is becoming a primary need in many fields of human activity. Continuous and accurate measurements are often required also in absence of local and fixed stations. This scenario leads to the development of low cost portable systems and to the design of innovative architectures, thanks to the availability of new technologies and sensors. The full system here proposed - easily integrable on a CMOS technology - is based on a hot wire anemometer, provided by Telecontrolli SME, and a suitable heater feedback that achieves, thanks to a dedicated algorithm, a novel portable solution with a robust design, without moving parts and small dimensions. It is suitable to operate up to 50°C and provides accurate wind speed and direction measurement.
