Abstract :
In order to acquire synchronous multi-information in precision agriculture, a farm field information measurement instrument with GPS position function was developed. This instrument, which mainly consists of a single-chip microcomputer (SCM), a keyboard, a LCD display, several sensors and a GPS receiver, was designed to synchronously integrate the signals from both sensors and GPS receiver. In this paper, we took soil water content acquisition as an example. And results had showed this device worked very well with a SWR-2 sensor and GPS25 receiver in respectively obtaining high-precise multiple soil moisture information of vegetable terra, cropland and gravel terra. In addition, the following plane and section tests using the instrument and its corresponding interpolation analysis with software Arc View also afforded a feasible and effective method for further soil moisture researches
