Circuit Simulation for Wireless Mini-drifting Buoy in Shallow Sea

Ocean buoys is an important tool of Marine Environmental Monitoring, The design of drifting buoy plays a significant role in field of shallow sea environmental monitoring. In order to solve the problem that the shallow marine physical parameters acquisition costs are high and the accuracy of data is low, this paper designed a mini-drifting buoy in shallow sea based on AT89S51 single-chip microcomputer, which were used in measuring shallow seawater temperature, salinity and depth. It is low cost and easy to move. It is not only can wireless remote control, but also can " Beidou " positioning. Moreover, the data is accurate and the mini-drifting buoys in shallow sea can return real-time data as soon as possible.
