A communication device and method for low-power irrigation facilities nfc

The present invention discloses a communication apparatus and method for low-power irrigation NFC-based device comprises a master MCU, the solenoid valve drive circuit, voltage regulator and boost unit, the master MCU to drive the solenoid circuit and stability and pressure boosting unit is connected, further comprising a memory for receiving the NFC regulation parameter update, the NFC unit internal memory through the internal data transmission I2C communication interface integrated with the master MCU, via an internal integrated antenna RF interface with the external sensor connection. When carrying out the present invention Irrigation Control parameter update, i.e., the memory device NFC target device is a radio frequency card emulation mode, and not actively generate a radio frequency field, and uses load modulation parameters return irrigation NFC initiator device, while the device may be initiated by NFC fast write irrigation parameters, and update the irrigation parameter settings. On the other, when the excess energy in the energy storage NFC capture function is in operation, the memory may be captured NFC to other device operation.
