A multi-sensing reconfigurable platform for gas applications

The production of hazardous gases due to different physicochemical reactions in gas industries have raised the need of autonomous sensor tag. However the adaptation of remotely controlled sensor tag is still suffering with many challenges, among which power consumption, selectivity and durability are the most prominent problems in gas application. Therefore in this paper, a reconfigurable multi-sensing platform is presented for gas applications. A low power ring-oscillator based temperature and tin-oxide based gas sensors are utilized to indicate the temperature and type of the gas with a total power of few μW's. The processing unit is designed on a heterogeneous ZynQ platform and a passive radio frequency identification (RFID) tag is designed to provide communication between the sensors and the processing unit.
