一种高性能超低功耗流量计设计

The Desig n of One Kind of Flowmeter With Utra-Low Power Consumption and Hig h Performance

本文介绍的流量计以德州仪器公司生产的超低功耗单片机MSP430F1121为核心,干簧管为传感器,液晶显示,其功耗极低,整机的工作电流仅为75μA特别适合一次性电池长久供电。

The flowmeter introduced in this paper takes the MSP430F1121CMOS chip produced by the TI as the core,the clarinet as the sensor and the LCD as the display device.It's consumption is very low.The max-imal current of this system is no more than75μA.So,it is adapted to the power supplied by the battery especially.
