Abstract
Real-time monitoring of Ammonium (NH4 +) concentration level in the soil would improve the management of the nutrients in smart agriculture. This paper reports the development of the F-MWCNT/ZnO nanocomposites based miniature sensor arrays for real-time monitoring of NH4 + in the paddy field. Screen printing of Copper (Cu) electrodes over the fiber epoxy followed by a spin coating of F-MWCNT/ZnO active layer structure was found to have a proportional impedance change with NH4 + concentration levels. The multiplexed sensor arrays were designed and tested with the standard and extracted water samples from the field. The sensor offers a higher sensitivity of 67.13 mM/ Ω in the linear range of 1 -10 mM NH4 +. Further, sensor arrays were facilitated using an IoT enabled NodeMCU microcontroller platforms for real-time monitoring of NH4 + concentration levels in the paddy field
