A wireless monitoring sensor of a lightning arrester comprises a current transformer, an operational amplifier, an AD converter, an MCU, a lightning counter, a display screen, a wireless communication module and a solar cell. The current transformer is arranged in the grounded loop of the lighting arrester. The current transformer is successively connected with the operational amplifier and the AD converter in series and is then connected with the data input end of the MCU. The lightning counter is arranged in the grounded loop of the lightning arrester, and the output end of the lightning counter is connected with the data input end of the MCU. The display screen is connected with the data output end of the MCU. The wireless communication module is connected with a bidirectional data end of the MCU. The solar cell is connected with the operational amplifier, the AD converter, the MCU and the lightning counter respectively. Through combined application of wireless network technology and a lightening arrester state monitoring sensor, the wireless monitoring sensor of the lightning arrester has functions of preventing a risk of introducing lighting current into a control chamber, and eliminating potential safety hazard of lightning arrester online monitoring equipment in overvoltage operation state.
