| Abstract: | The farmland water potential （FWP） soft-sensing network with star-scheme is composed of several crop micro-environment data acquisition nodes and FWP soft-sensing station. The data acquisition node （slave computer） in this network is based on ATmega128 MCU, the sensor configuration is accord with the Technical Requirements of FWP softsensing. After data-pretreatment, the all kinds of micro-environment data gathered are transmitted to FWP soft-sensing station （host computer） by RS-485 serial bus or wireless data-transmission module, both estimation of FWP value and remote monitoring of farmland environment are achieved. |
