The invention relates to a
water environment monitoring node based on ZigBee
wireless technique. The prior technology has long monitoring period and large work intensity, and cannot reflect dynamic variation of
water environment. The invention includes an
electric power management module, a
water quality parameter acquisition module, an MPU module and a ZigBee
radio frequency module. The equipment adopts an MSP430F149 MPU, for analyzing and
processing water environmental parameter, and controls the operating status of the ZigBee
radio frequency module and the
water quality parameter acquisition module. The MSP430F149 processor is interconnected to the
water quality parameter acquisition module through a 12 bit A / D converter self integrated with the MSP430F149 processor, and is interconnected to the ZigBee
radio frequency module through an SPI serial interface, meanwhile also controls a power
supply management module to supply power through an
analogue switch, so as to achieve the goal of energy-saving. The invention has low cost, and low
power consumption; can be arranged in
water environment for a long term, execute multiple parameter real time monitoring to the water environment, and complete the high-efficiency transmission of data, thereby having wide applications prospect in the water environment monitoring.
