Sensor Node-Based Smart Irrigation System with IoT Framework

Agricultural production constitutes the backbone of the Indian economy, so modernization is essential. The motivation for this paper comes from developing countries, much of which depend on agriculture and climate conditions. Internet of Things (IoT) technology is played a key role in overcoming the backwardness of traditional agriculture, improving crop production, preventing crop damage and efficiently using water. This paper proposes the deployment of a smart irrigation system based on portable prototypes using capacitive soil sensors based on qualitative designs and sensory data collection methods from agricultural fields. Sensors are connected to the Internet via wirelessly in this case. Through wireless sensor nodes, data from the sensors is sent to the cloud. The IoT frameworks analyze and process the collected data. This is followed by regular notifications being sent to the farmer's mobile phones or Application Programming Interfaces (API) application. Changing soil temperatures and moisture can be tracked by farmers. This can prevent unnecessary water waste. In this paper, we discuss various experiments conducted in this context and present a comparatively low-cost wireless irrigation system.
