| Abstract: | A new methane sensor array based on thick film technology is investigated, and the processing methods is introduced. A high precise signal processing circuit is designed corresponding to this methane sensor array. The circuit can send acquisition data to PC and the PC software receive it and give real-time analysis, graphic displaying to users, The PC gives a warning message when the concentration exceeds the value set by the user. The PC software can control the single chip and choose any one of the sensors to work while the sensors work in turn at the ordinary times. |
