Abstract:Because of the requirement of step charge and remote gathering data of water meter, design a wireless remote intelligent water meter. The meter is based on 430 MCU and Si4432, the MCU power consumption is low, the wireless transceiver chip transmission is distance. Describing the theory of water meter, hardware framework, software idea,procedure of remote transmission and receiving. Experimental results show that within a kilometer's distance, the transmission rate is lower than 100 Kpbs, it can achieve the integrity of the data transmission and the steps of the charging function. The water meter has well characteristics, including the costs is low, power consumption is low, preventing water is well, it’s the trend of intelligent water meter.
