To provide a water leakage detection system which is highly reliable even when a communicable data amount is limited.SOLUTION: A water leakage detection system comprises two or more sensor terminals and a computation section between which wireless communication is performed. Each of the sensor terminals converts a measurement signal including a frequency component into data and transmits data according to a frequency resolution based on a measurement condition received from the computation section into the computation section. The computation section receives data according to a first frequency resolution and, when determining from the received data that water leakage occurs, transmits a measurement condition which is a second frequency resolution lower than the first frequency resolution to each of the sensor terminals.SELECTED DRAWING: Figure 11 【課題】通信可能なデータ量が制限された場合であっても信頼性の高い漏水検知システムを提供する。【解決手段】２個以上のセンサ端末と演算部とが無線通信する漏水検知システムであって、前記センサ端末のそれぞれは、周波数成分を含む測定信号をデータに変換し、前記演算部から受信した測定条件に基づく周波数分解能に応じたデータを前記演算部へ送信し、前記演算部は、第１の周波数分解能に応じたデータを受信し、受信されたデータから漏水であると判定すると、前記第１の周波数分解能より小さな第２の周波数分解能となる測定条件を、前記センサ端末のそれぞれへ送信する。【選択図】図１１
