The present invention relates to a system for remotely and wirelessly detecting water leak, which comprises a water leak sensor, which is able to shield an electromagnetic wave, and detect a water leak in a non-vacuum status, thereby being capable of precisely detecting a water leak wirelessly at a remote place. According to the present invention, the system for remotely and wirelessly detecting a water leak comprises: a water leak detector (104) installed on one side of a pipe to receive a command signal from a central controller (102) through wireless communication, detect a water leak in accordance with the received command signal, and transmit the detected water leak information to the central controller (102) through wireless communication; and the central controller (102) connected to the water leak detector (104) through wireless communication to transmit the command signal to the water leak detector (104) by using a water leak detection application software at a remote place, and receive the water leak information. The water leak detector (104) includes a water leak detection sensor means (120). The water leak detection sensor means (120) comprises a circuit board (132) which includes a lower cap (124), an upper cap (126), and a water leak detection sensor (130) which detects a water leak; and a pressure detection unit (134) which detects a pressure. Here, on an upper surface of a floor of the lower cap (124), a first shield plate (136) is installed to block electromagnetic waves. On an upper surface of a floor of the upper cap (126), a second shield plate (138) is installed to block electromagnetic waves. On one side of an upper surface of the upper cap (126), a pressure detection unit (134) is installed. The pressure detection unit (134) checks the vacuum status of the inside after the lower cap (124) is engaged with the upper cap (126). 본 발명은 전자파를 차폐함과 아울러 무진공 상태에서 누수를 감지하는 누수감지센서를 구비함으로써, 원격지에서 무선으로 누수를 정확하게 감지할 수 있도록 한 원격 무선 누수 감지 시스템에 관한 것으로, 본 발명은 배관의 일측에 설치되어 무선통신을 통해 중앙제어기(102)로부터 명령신호를 수신받고, 수신된 명령신호에 따라 누수를 감지한 후, 감지한 누수정보를 무선통신을 통해 중앙제어기(102)로 보내는 누수감지기(104)와; 상기 누수감지기(104)와 무선통신을 통해 연결되어 원격지에서 누수감지 앱 소프트웨어를 이용해 누수감지기(104)로 명령신호를 보내고, 누수정보를 수신받는 중앙제어기(102)를 포함하되, 상기 누수감지기(104)는 누수감지센서수단(120)을 포함하며, 상기 누수감지센서수단(120)은 하부캡(124)과 상부캡(126)과 누수를 감지하는 누수감지센서(130)를 포함하고 있는 회로판(132)과 압력을 감지하는 압력감지부(134)를 포함하고, 여기서, 상기 하부캡(124)의 바닥 상면에는 전자파를 차단하는 제1차폐판(136)이 설치되어 있고, 상기 상부캡(126)의 바닥 상면에는 전자파를 차단하는 제2차폐판(138)이 설치되며, 상기 상부캡(126)의 상면 일측에는 압력감지부(134)가 설치되어 있는바, 상기 압력감지부(134)는 하부캡(124)가 상부캡(126)이 결합 후, 내부의 진공 상태를 체크한다.
