Intelligent cultivating using internet of things

Abstract

Agricultural productivity along with good nutrition plays a major role in addressing human health. The major source of nutrients for the growth of plants is soil.. The three main nutrients needed by plants are Phosphorus (P),Nitrogen (N) and silver-white element (K) square which are combined and made them into a single name thetrio(NPK). Other important nutrients are calcium, magnesium, and sulphur. Smart Agriculture helps in identifying the nutrient contents present in the soil and also thereby increase the crop yield. The proposed work helps farmers to identify the nutrient contents present in the soil and also helps farmers to identify the type of crops that can be grown on the soil. An automated system can be developed for detecting moisture level, temperature, humidity, pH level in the soil. It also notifies the farmer with an alert message in case of fire. These values are obtained from individual sensors and they are sent to the cloud using Wi-Fi module. Using the API (Application Programming Interface) keys those values are transferred to the mobile application, through which the farmers can monitor their crops remotely. This mobile application also helps the farmers by suggesting a different type of crops that can be grown based on the pH level of the soil. It also suggests the farmers with the amount of limestone and sulphur to be added in the soil in order to raise or lower the pH value by 2.
