Title Design of Agricultural Monitoring System Based on
MSP430F5438A--Driver Design
Abstract
Intelligent monitoring system has wide application prospect.It has a very important practical application in many industries.More and more applications use single chip microcomputer as control core through the microcontroller to monitor the object intelligent control. Agricultural monitoring is an important means of modern agricultural production process.It can realize the automation and modernization of agriculture. As the product of modern automatic detection, it is the future direction of development. It can be in accordance with the mode of operation of the set without human management. As a result,it is widely used in production, life and human society. I combine with msp430f5438a microcontroller and design of monitoring system which can complete field data acquisition, storage and can real-time collect all kinds of sensor output 0-5V/0-3V analog voltage value, 4-20mA current signal and other digital sensor such as electronic gauge signal. This paper completes the design and debugging work of driver.At the same time ,I complete the whole system debugging work.
