Title Temperature acquisition system based on MSP430
Abstract
Temperature control the appearance prospect, in various industries will occupy an important position, More and more applications in the field to control the core of the temperature information storage, real-time control, detection and digital display. This has an important role in production safety, improve product quality, energy conservation and so on.
This design is set out from the lower development costs, expand the scope of application, improve the stability and reliability of system operation is designed, using MCU MSP430G2 as control core, with a single bus digital temperature sensor DS18B20 to complete the collection of temperature signal and temperature as a number of buildings display on the LCD1602, through the PC remote monitoring operation, and ultimately achieve the temperature acquisition, display, alarm, set. And this paper focuses on the system's hardware structure and software programming design process.The temperature measurement system hardware consists of six parts: power supply and reset module, acquisition module, sound and light alarm module, serial communication module and display module.
In this paper, based on MSP430G2 eventually, DS18B20 as temperature sensor, the temperature in the form of digital display on the LCD1602 temperature sensor, and single chip microcomputer with the PC via a serial port communication interaction.
