IoT Enabled Smart Farming: A Controlled Environment Agriculture Application

Horticulture is the science of sustainable production, advertising and marketing the intensively cultivated food and decorative plants. The major intricacy in horticulture is maintaining the temperature within the controlled environment such as polyhouse or green house which leads to plant damage like root rot, leaf spots, downy mildew. This results in IoT of human intervention in checking the temperature periodically and provide remedial measures to maintain it. In order to overcome such issues this work proposes an IoT-based Automatic Temperature Controller (ATC) system using Arduino board interfaced with the environmental data by deploying Internet of Things (IoT). The proposed work incorporates two phases: (i) Collection of data for the different floral plants and uploading it to the IoT cloud (ii) Implementing the hardware part using Arduino UNO kit for ATC system. The ATC system gets the values of temperature and humidity from DHTII sensor where, the entire system is connected to the Arduino microcontroller which compares the recorded value with the threshold value set by user in cloud. The motor will be turned on by the controller being the observed temperature is found larger than the threshold value. The proposed system has been tested on different floral plants that are of high productivity in and around Hosur, Tamil Nadu circumstances namely Gerbera daisy, Button rose, Chrysanthemum and Rose. This work can be extended for other agricultural application purposes like creepers, mushroom cultivation etc.
