Abstract :This paper presents a wireless hydrological data transmissionsystem, whichis composed of the remote central control unit and
the local controllers . A wireless datatransmission module is made as the central control unit , whichcan communicate wirelessly withthe
local controllers consisting of ARM2132 single- chip processors and nRF905 . The usage of the wireless transmissionsystemis introduced
in order to acquire hydrological data fromdistributed test points . A systematic solution to design hardware and software of the wireless
transmissionsystemis also developed and analyzed inthe paper .
