基于MSP432的多传感器数据采集与动态显示实验设计

Design of experiment on wireless multi-sensor data acquisition and dynamic display based on MSP432

针对传统的无线数据采集存在着距离短、功耗高的不足,设计了一套通信距离较远、超低功耗的无线采集系统。系统以德州仪器最新高性能低功耗微处理器MSP432的主控单元,配合温湿度传感器、光敏电阻,对温度、湿度、光照度进行采集,通过无线模块实现数据的无线传输,并显示在LCD显示器上。通过该实验,学生能很好地学习嵌入式硬件和软件的设计开发过程,培养学生的团队协作能力。

In view of the shortcomings of the short distance and high power consumption in traditional wireless data acquisition,a wireless acquisition system with the long communication distance and ultra-low power consumption is designed.This system uses the main control unit of the latest high-performance and low power microprocessor MSP432 of TI,and in combination with the temperature and humidity sensors and photosensitive resistance,the temperature,humidity and light intensity are collected.The wireless transmission of data is realized through the wireless module and shown on the LCD display.Through this experiment,students can learn the design and development process of embedded hardware and software well and cultivate their teamwork ability.
