According to the intelligent sensor system of composition and range of applications, with fully taking into account the parameters of the connection between components of co-ordination, we chose a good usability, high reliability and low cost components composed of the entire measurement system, with controlling and dealing with in 80C51 microcontroller, the system had the temperature and pressure parameters with automatic measurement, amplification, A/D conversion, the weak signal locked amplification, as well as Phase Sensitive Detection(PSD), common-mode signal rejection, the collected signal de-noising processing, cross-sensitivity of the decoupling and show the results. It also has a self-test. Automatic temperature compensation and on-side medications and other functions.

It can be said that from space to sea, the basic necessities of daily life from a variety of complex engineering systems cannot be separated from various sensors and sensor technologies and play an enormous role in the growing development of the national economy. however. The smart sensors curr
