Abstract: Multi-address digital water-potential remote system(SSY-l)and digital water-potential recorder(SSJ-l) have been made recently. The system consists of the sensor and digital water-potential instrument of observation. This paper describes the principle and the components of the system and also presents the design and the results of the observations. Such problems as accurancy, error analyses and interference rejecting transmission usually lying in many conventional system are discussed as well.A new sensor and a decode circuit have been designed, following above analyses and discussions.Viewed from the data obtained from observations for one or two years, the idea of the design proved to be correct and useful. This can be extended to other detection and remote system of low variation.
