Abstract:
This paper describes an amperometric sensor module for gas concentration measurement. A module can be used for many types of electrochemical gas sensors without major hardware changes. Device is based on AVR ATmega8 microcontroller. As signal processing circuit a specialized integrated circuit LMP9l000 configurable via I2C interface is used. The concept of a measuring system composed of several modules dedicated for a gas sensors array is presented as well. System controls modules, collects and analyses their responses. It was designed with an emphasis on universality and modularity. The proposed equipment will be used as the core of electronic nose system employed for classifying and distinguishing different levels of contamination in air.
