The changing dynamics,non-linearity of soil moisture content,as well as other weather and plant variables requires real-time monitoring and accurate predictive model for effective irrigation and crop *** this paper,an improved monitoring and datadriven modelling of the dynamics of parameters affecting the irrigation of mustard leaf plant is *** IoT-based monitoring framework is implemented using ESPresso Lite V2.0 module interfaced with different soil moisture sensors(VH-400),flowmeter(YF-S201)as well as Davis vantage pro 2 weather station to measure soil moisture content,irrigation volume,and computation of the reference evapotranspiration(ETo).The data collected including plant images were transmitted to the Raspberry Pi 3 controller for onward online storage and the data are displayed on the IoT *** combination of both soil moisture and ETo values was used for scheduling a drip irrigated plant grown in a greenhouse for 35 days.A total number of 20,703 experimental data samples are collected from the IoT-based platform was further used for data driven modelling through system identification in *** result shows the development of different predictive models for soil moisture content *** ARX prediction model is found to perform better than the ARMX,BJ and State space model in terms of estimated fit of 91.31%,91.09%,91.08%,and 90.75%***,a robust monitoring framework for irrigation system has been developed,while the performance of the identified ARX model is promising to predict the volumetric soil water content.
