A COMPUTER EMBEDDED CAPACITIVE SENSORS ARRAY

Interdigitate capacitive sensors are promising devices for gas sensing in terms of fabrication costs and ease of integration. The aim of this study was to investigate a novel arrangement of interdigitate capacitors for air quality monitoring with high sensitivity and resolution, using low cost devices at room temperature. The system is fully controlled (through audio device board) by a personal computer which feature represent a great advantage in terms of cost, versatility and ease of use. The paper will describe the characteristics of the interdigitate capacitors, the electronic system and experimental results
