基于MSP430的温室多路数据采集系统

Multi-channel Data Acquisition System in Greenhouse Based on MSP430

设计了一种以MSP430单片机为核心模块的温室多路数据采集系统,用以采集温室内的多路环境参数。采用信号调理电路和MSP430单片机内部A/D转换模块相结合的方式,实现了从模拟信号到数字信号的采集和转换,转换精度可达到10位。该系统具有结构简单、功耗低、工作稳定和可移植性较强等特点,可广泛应用于多路模拟信号的数据采集。

Designed a kind of multi - channel data acquisition system take MSP430 as the core processing module for the collection of the parameters of the multi - channel environment in greenhouse. And the use of signal conditioning circuit and A/D conversion module of MSP430 achieve the sampling and the converter from analog signal to digital signal, the precision of conversion is up to l0 -bit. The system is simple, low -power, stability and highly portable. It can be widely used in multi -channel analog signal acquisition.
