| Abstract: | A design method for data acquisition system of pressure sensor with high precision based on wireless sensor networks is introduced here. The technology of Zig Bee of wireless sensor networks is embedded in upper computer and lower computer of the system and fulfils the purpose of communication in bad environment. The system also expands digital output interface of RS-485 and analog output interface of 4~20 mA, which improves applicability of the system. In actual application, this system is stable and reliable and the precision of the sensor can reach 0.07 %. |
