LoRa Technology Based Farm Irrigation Control System

Precision Agriculture is becoming the recent trend and backbone of the country, which helps the farmer to have more yield and the effective and efficient use of resources automatically. Various technologies associated with IoT will contribute for this precision agricuture depending upon the requirements. In this paper a farm irrigation control system is proposed, which makes use of LoRa technology for the purpose. LoRa (Short for Long Range) is a practical wireless platform for Internet of Things (IoT) that connects sensors to the cloud and enables real-time communication of data and analytics that can be leveraged to improve efficiency and productivity. The distinct features such as long battery life, long distance communication, etc., of LoRa technology used to create a wireless sensor network, which is a collection of wireless sensor nodes which are communicating with each other to transfer the soil moisture value from the agriculture field to a server. The user can make use of this information to take control actions that can be helpful in increasing crop efficiency and productivity. The proposed work makes use of LoRa communication between LoRa transmitter and receiver, serial communication between LoRa receiver and NodeMCU, Wi-Fi based IP communication between NodeMCU and server. LoRa communication can take place even in the absence of internet and base station. Thus, this system shall benefit farmers mainly in remote region where internet connectivity is low. The effectiveness of the system is realised with the justified results.
