Energy efficient wireless sensor network and low power consumption station design for an urban water level monitoring system

In the context of wireless sensor networks (WSN), a design of an energy efficient wireless data collecting network and a low power water level monitoring station have been proposed in this paper. Different low power consumption sub-Ghz wireless modules have been compared in this paper, and a most efficient wireless module have been selected in order to design a wireless sensor network. This power efficient wireless sensor network have been designed to connect to many water level monitoring stations and transmit its data to a remote centre. In order to ensure a longterm operation in environment without the grid power supply, solar power supply have been selected and a low power consumption design of a water level monitoring station is also proposed. Finally, the power consumption of the proposed station with wireless sensor network module has been calculated to prove the energy efficiency. With the advantage of a low power consumption and low cost design, the proposed wireless sensor network and water level monitoring station can be applied widely in urban environment in developing countries like Vietnam.
