RFID sensor for water leakage detection of water pipe

The invention discloses an RFID sensor for water pipe water leakage detection, which comprises a first radio frequency transceiver, a second radio frequency transceiver, a coding module and a sensing module, and is characterized in that when the RFID sensor is used for water pipe water leakage detection, the sensing module detects the current state of a detected water pipe in real time and generates sensing information representing the current state of the water pipe; the first radio frequency transceiver receives radio frequency signals and transmits the radio frequency signals to the coding module, the coding module loads coding information in the radio frequency signals and then sends the coding information to the sensing module, and the sensing module loads sensing information in the radio frequency signals and then sends the sensing information to the second radio frequency transceiver. The second radio frequency transceiver transmits a radio frequency signal with coding information and sensing informati
