Smart Agriculture Fertilization System By Using A Unified Multi Parameter Sensor

Abstract

India needs to use intelligent and effective farming practices due to the growing population which results stress on agricultural resources. Inefficient use of fertilizer in conventional agriculture, often leads to reduced crop yields, increased costs and environmental degradation. The main aim of this study is to develop a IoT based Smart Agriculture Fertilization System using Unified Multi-Parameter Sensor (UMPS). The proposed integrated sensor monitors real-time soil condition and measures soil moisture, pH, temperature, electrical conductivity and nutrients like Nitrogen (N), Phosphorus (P), Potassium (K) concentrations simultaneously. The proposed method consists of microcontroller-based hardware and the software by using Raspberry Pi 3, Python and a cloud-based dashboard for data visualization. The performance of sensor was tested at various agricultural soil locations in Sangli District of Pune Region, southeast of Maharashtra, India to evaluate performance. The sensor accuracy was compared to standard laboratory soil reports. The obtained result shows that accuracy was more than 95% to determine soil nutrients (NPK) and other selected parameters.
