PROBLEM TO BE SOLVED: To provide a watering system capable of performing watering in which an intention of a culture person is reflected in real time under a variable situation while performing automatic watering.SOLUTION: A watering system 8 comprises a data acquisition module 9 and a data processor 10. The data acquisition module 9 comprises: a measurement value sending part 12 which sends a measurement value measured by a soil moisture sensor 11 with first identification information according to an instruction, then sends the measurement value with second identification information for every prescribed time. The data processor 10 comprises: a measurement value reception part 15 for receiving the sent measurement value； and a determination part for, when the first identification information is added to the measurement value, performing first determination indicating a fact that, watering should be performed to the soil unconditionally, and storing the measurement value, and when the second identification information is added to the received measurement value, considering the measurement value and the stored measurement value for performing second determination of whether or not watering should be performed to the soil.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2020,JPO&INPIT【課題】自動灌水を行いつつも、刻々変化する状況下での栽培者の意図をリアルタイムで反映した灌水を行うことができる灌水システムを提供する。【解決手段】灌水システム８は、データ取得モジュール９とデータ処理部１０とを備える。データ取得モジュール９は、指示に応じて土壌水分センサ１１による測定値を第１識別情報とともに送信し、かつ所定時間毎に該測定値を第２識別情報とともに送信する測定値送信部１２を備える。データ処理部１０は、送信された測定値を受信する測定値受信部１５と、該測定値に第１識別情報が付随している場合には、無条件で土壌に散水を行うべき旨の第１判定を行うとともに該測定値を記憶し、受信された測定値に第２識別情報が付随している場合には、該測定値及び記憶されている測定値を考慮して土壌に散水を行うべき旨の第２判定を行う。【選択図】図２
