Traditional coastal environment monitoring with wireless sensor networks（ WSNs） node disadvantage of high-cost

short of expandability

short-distance communication

a design method of WSNs node for coastal environment monitoring based on open Arduino platform is proposed. The method meets the coastal environment monitoring requirements

firstly

selection and customization are carried out on micro control plate of sensor node

as well as the design framework of node function module; then solutions to some key problems in the hardware and software design of sensor node

such as

optimization of power supply

fusion of multiple communication mechanism and long distance communication are given respectively. Practical application result shows that the WSNs constructed by designed node can real time and continuously collect environment in monitoring area

upload to server reliably

communication distance between two adjacent nodes can reach 1000 m at most. The designed WSNs node functioned well with low cost of development

rich interfaces

strong scalability

concenient networking

the sensor node not only satisfies real time acquisition requirement of data acquiring of coastal environment observation

but also apply to real time environment monitoring of freshwater

it has a wide application prospect.
