WIPO Patent Application WO/2023/132288
Kind Code:
A1
Abstract:
[Problem] To improve measuring accuracy by installing a sensor device in a position in which there is no impact due to objects. [Solution] This information processing device comprises: a transmission coefficient calculating portion for calculating a transmission coefficient from a time waveform of a transmitted wave which, among incident waves sent from a transmitter that sends electrical signals including said incident waves to one of a pair of probes each having an antenna, has been received by a receiver for receiving the transmitted waves that have been transmitted through a medium of a first range; and a determining portion for determining whether an object is present in a prescribed range in the medium, with respect to the pair of probes, on the basis of the transmission coefficient. The present invention also makes it possible to control irrigation of crops in accordance with a measurement result from a moisture sensor. The present invention can thus contribute to improving the efficiency of water use in agriculture.
