The invention provides a soil moisture content monitoring system based on an RFID wireless sensor tag, the system comprising an RFID wireless sensor node, a service layer and an application layer. TheRFID wireless sensor node and the service layer communicate with each other through a ZigBee wireless network. The remote communication between the service layer and the application layer is realizedthrough a WiFi or 4G network. The RFID wireless sensor node is composed of an RFID wireless sensor tag, a single chip microcomputer module, a ZigBee module and a power module. The RFID wireless sensor tag, the power supply module and the ZigBee module are respectively connected with the single-chip microcomputer module, and the RFID wireless sensor tag, the power supply module and the ZigBee module are connected with the single-chip microcomputer module. The RFID wireless sensor tag is composed of an RFID chip, a dipole antenna and a humidity sensor. The RFID tag chip adopts Impinj X-2K, which meets the second generat
