| Abstract: | Aiming at difficult wiring and scattered distribution in some industrial fields,this paper briefly introduces the WIA-PA technology,and designs a wireless temperature transducer based on WIA-PA with the high performance and low power consumption 16-bit MCU MSP430F5438A as the core.Thermocouple temperature measurement circuit is built for compensation of the thermocouple at the cold terminal.The designs of communication program between wireless and temperature acquisition module are given.Tests on temperature acquisition prove that the wireless temperature transducer can communicate stably and reliably with a measuring precision within 5‰. |
