Wireless Digital Water Meter with Low Power Consumption for Automatic Meter Reading

Recently, several papers for reading meters remotely using RFID/USN technologies have been presented. In the case of wireless water meters, there has been neither commercial product nor paper. In this paper, we describe the design and implementation of wireless digital water meter with low power consumption. We use magnetic hole sensors to compute the amount of water consumption. The meter of water consumption is transferred via ZigBee wireless protocol to a gateway. Low power consumption design is essential since a battery should last till the life time of water meter. We suggest that dual batteries having 3 V, 3000 mAh, would last 8 years by analyzing the real power consumption of our water meter.
