Design and Development of Soil Monitoring System for Precision Farming On Small-Scale Outdoor Farm

The agricultural sector is of paramount importance in enhancing the national economy and serving as a primary food source. Given the limited availability of arable land, there is a pressing need to enhance agricultural productivity through precision agriculture to provide affordable food source. Precision agriculture aims to optimize the timing, quantity, and location of farming practices. Nevertheless, the full potential of agricultural technology innovations is yet to be harnessed by farmers, resulting in suboptimal utilization of these technologies. To address this issue, there is a growing imperative to monitor plant health and crop production in real-time using sensors and agricultural technology. Therefore, a tool has been developed to enable comprehensive plant health measurements, encompassing parameters such as ambient temperature, soil moisture, air humidity, light, CO2 levels, and the levels of essential nutrients, namely Nitrogen, Phosphorus, and Potassium (NPK). This data is seamlessly processed by the Node-RED server, which presents the sensor parameter information through visually appealing graphs and icons. This intuitive data presentation empowers users to gain a profound understanding of the information and conduct in-depth analyses of plant condition and nutritional aspects. The tool showcased in this product exhibits an impressive success rate of 100% in delivering on these objectives.
