Smart Decision Maker and Monitoring System for Modern Agriculture based on Internet of Things

More than 20 percent of our nation's GDP is gen-erated by the agriculture sector, which serves as the foundation of the economy. Agriculture is defined as the science and art of cultivating the flora and fauna. Soil is an important natural resource and is frequently regarded as one of the most significant natural resources for food production. Lack of knowledge and instruments is the basic problem in maintaining agricultural resources. The majority of farmers are unable to assess the condition of their crops and land. But, the agriculture sector faces challenges like water scarcity, climate change, and low production due to outdated farming practices, wasting time, money, and fertility. The main contribution of research is to provide farmers with information and appropriate solutions. As a result, it plays a crucial role in promoting constructive change in the agriculture industry and enhancing the welfare of farming communities. In our proposed system, a portable device collects soil information through a few sensors. Soil moisture, humidity, temperature and pH sensors detect the condition, then data analysis provides a decision according to the data. Our decision will be provided to farmers through an SMS alert system. Using this device, the irrigation of water will be reduced and fertility will be easier for the farmers. Additionally, a web-based monitoring system is linked to an IoT platform named Blynk in this system. The adoption of smart farming technology increases modern agricultural output and makes it possible to plant. We have used the Arduino UNO on the backend to implement our model and build the suggested system.
