The Wireless Digital transmission of Intelligent Flux Meter [资料来源：http://think58.com]

Abstract

    These papers introduce a low power consumption intelligent flux meter by using the MSP430F149 single microcomputer. And reported that the measure principle of liquid volume and temperature .the system construction constitutes and its hardware design .the low power of the system consumes the design with realizes. And own the RS485, correspondence connect and nRF401 wireless correspondence connect .own the remote reader and centralized management etc. function . [版权所有：http://think58.com]

Considering the new achievements of micro controller technology MSP430 and other relevant technology, the practical low power consumption techniques for portable intelligent instruments are studied in this paper. This is valuable to designing the low power consumption performance of portable intelligent instruments. we design is based on the new type and super-low-power 16bits system----MSP430 F149. Take advantage of  ultra-low-powerhigh-integration, this system can be used to thecondition of battery supply and limited space or portable application.With this foundation,  as the memorize of ECG. LCM0826B is used as the LCD display of the system. So this circuit is simplified greatly. It must be applied widely and surely has a promising prospect. [资料来源：THINK58.com]
