The ultimate aim of this concept is to reduce labour demands on farmers, allowing them to save money for increased stockpiling. Farmers typically see a decline in income due to bad harvests. Among the many significant reasons that contribute to this are the lack of nutrients, the moisture of the soil, the variations in temperature, and so on. As a result, the prevalence of diseases in the crop reduces both its quality and its yield. New, state-of-the-art IoT gadgets can effortlessly monitor agricultural regions and report on their current state. In this article, we'll go over the steps required to construct a smart agriculture system utilizing state-of-the-art technologies like Node MCU, the Internet of Things, Android, Wireless Sensor Networks, Keeping a close eye on weather trends and the early detection of plant diseases is essential for increasing agricultural output. The proposed system can monitor temperature, humidity, and moisture using sensors using NodeMCU, and it can send SMS alerts and a notification on the application created for the same on the farmer's smart phone over Wi-Fi/3G/4G. The technology uses cellular networks and the Internet protocol to facilitate a two-way communication connection. Farmers may be able to detect plant diseases early using this reliable, non-destructive method. Three different types of tomato plants were used to develop an Internet of Things (IoT) based approach to plant disease diagnosis (two infected and one healthy).
