LoRa - Powered Smart Agriculture System for Monitoring and Controlling

As the technology advances the traditional farming is heading towards smart agriculture. In smart agriculture the various parameters like soil moisture levels, temperature, humidity, and presence like NH3, CO2 etc., at field and crops are analyzed. This data from sensors is communicated to microcontroller for necessary processing and action. Usually, data is communicated using internet. But in rural and extreme regions where internet is not available and has poor connectivity then communication wont possible. In these cases, Long Range Network (LoRa) can be optimum communication technique. LoRa technique provides low cost and effective communication network without use of internet. In this work LoRa based smart agriculture system is implemented. The sensors located in farmland distanced at few Kilometers are communicated and operated using LoRa. The system monitors temperature, humidity and gases in real time and automatically controls water level in farms by enabling the features of smart irrigation system. The prototype of LoRa transmitter and receiver are developed that works without internet.
