Neolithic Demographic transition resulting the reduction of habitable land for cultivation. Hence the smart agriculture is the only way to cater higher food demand. The farming community of developing countries like India needs Kisan Samanvayam with futuristic technologies for financially viable cultivation. Technology place vital role in economically nourishment of soil fertility and crop management. In this regard we proposed IoT-ML framework for remotely assessing the soil nutrients (N, P,K), PH and early stage detection of crop deceases. Android APP which is a part and parcel of the frame work enable the farmer to have real time visual statistics of the soil nutrients, notifications and suggestions regarding to the crop management. JXCT Soil NPK sensors, PH sensors, Dual Core ESP32 Controllers, Firebase Cloud and Random Forest Decision Tree machine Learning Algorithm, Micromlgen serve this purpose. Unlike Solitary sensor for entire field, we have divided a hector into four subregions for effective monitoring local region needs. The presence of IoT with TinyML increased the robustness of the framework and results are encouraging with sandy loam soil.
With the advent of the 21st century, comfort and efficiency started becoming a part of a common man’s life. Virtual assistants like Amazon Alexa and mobile applications like Google Assistant have tremendously helped in making Home Automation Systems more effortless and orderly. Efforts are still being made for better intra-connection of our homes. Home automation has created a great impact in the field of the Internet Of Things. In this paper, we have used the pre-existing technology of Alexa Echo to make Home Automation more cost-effective by enabling non-smart devices to react to the virtual assistant. In this framework, we proposed a smart node (relay) that can remotely control the connected electrical gadget using text/voice commands. The status can be monitored and controlled by the Alexa app remotely without the need for physical voice commands to Alexa. Further, room ambience, as well as emotion-based lighting, can be provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
