Dynamic reconfiguration in smart sensors' design

The dynamic reconfiguration provided by the modern programmable system on chip (PSoC) allows expanding the measuring area and the accuracy of sensors by using the alternative measuring circuits without of an additional external hardware. The reconfiguration is handled internally by the system in order to adjust settings and a measuring method to changing conditions. For example the sensor of the gas pressure with the full scale was designed. In this sensor the analog circuits and the measuring procedure are changed automatically from the steady state thermal conductivity way at vacuum to the temperature waves' method at the highest pressure. Another sensor of gas flow was designed on the base of MEMS and PSoC too. The real-time reconfiguration of SoC's hardware resources allows applying the most suitable circuitry for the broad band measuring.
