Abstract

The Texas Instruments microcontrollers in the MSP 430 series offer four ways to save power in operation in such a way as to allow for consistent reduction of the electricity consumed. Code Composer Studio programming environment also provides support in making low-power applications. In addition to these, the MSP430FR2433 microcontroller with ferroelectric RAM allows data to be stored even in the absence of power voltage. In view of these properties of the microcontroller, a data logger application has been developed to monitor the quality of the environment in a building. Given that the MSP430FR2433 microcontroller can process both analog and numerical signals, the device monitors the temperature, humidity, carbon dioxide concentration and amount of light present in the enclosure. Thanks to energy-saving mechanisms and the possibility of keeping information for an indefinite period without the need for energy consumption, the ambient quality monitoring device can operate for a long time in places without energy resources. The device has also been tested with good results for autonomous operation using solar energy and has also been used to determine the energy performance of buildings.

采用ti 430fr2433集成电路,降低系统能耗
MSP430系列中的德州仪器微控制器提供了四种在运行中节省电力的方法,从而可以持续减少电力消耗。Code Composer Studio编程环境还支持制作低功耗应用程序。除此之外,带有铁电RAM的MSP430FR2433微控制器允许即使在没有电源电压的情况下也可以存储数据。鉴于微控制器的这些特性,已经开发了一种数据记录器应用程序来监测建筑物中的环境质量。考虑到MSP430FR2433微控制器可以处理模拟和数字信号,该设备可以监测外壳中的温度、湿度、二氧化碳浓度和光量。由于节能机制和在不需要能源消耗的情况下无限期保存信息的可能性,环境质量监测设备可以在没有能源资源的地方长时间运行。该设备还经过测试,在使用太阳能的自主运行中取得了良好的结果,并被用于确定建筑物的能源性能。
