2 gas are discussed. CO2 sensor is prepared using polycrystalline ferrite material and deployed for detection. The system is designed with mixed signal based Cypress PSoC device CY8C29466-24PXI with PSoC Designer 5.1 as IDE. The high input impedance of on-chip PGA supports direct interfacing of CO2 gas sensor, whereas on-chip ADC ensures the preciseness in the data. The system is implemented to detect the presence of CO2 and could be extended to measure the concentration of CO2 gas in percentage unit.
">Nowadays, to keep pace with requirements of smart instrumentation of various sectors and reduce the design time, the use of programmable system on-chip is the best solution. Moreover, use of mixed signal array based PSoC would be most suitable to design an embedded system with more preciseness. In present paper, the details regarding hardware and software co-design for embedded system, which is dedicated for detection and measurement of CO2 gas are discussed.
