The Software Design of temperature detection based on PSoC
Abstract
As the development of the computer and automation technology and as the function device of sensor, convert, transmission and process, temperature detection becomes more and more important. It is a key technology tool in automation of detection, control and measure test. The article mainly introduces the software design of temperature detection based on PSoC. The software design is based on the PSoC Designer5.1 which is developed by Cypress. The important functions include the detection of temperature data, process, display and alarm. Through the set of the key, it can give an alarm. The paper also briefly introduces the characteristics of PSoC(Programmable System on Chip) as well as some of the configuration of the hardware design module. This system has many characteristics——little volume, low cost and working stability, and it is very useful to the engineering application.
