Design and Optimization of IoT Based Smart Irrigation System in Sri Lanka

In the field of agriculture, development of efficient IoT based smart irrigation system is similarly a valuable requirement for farmers. In this research, a low cost IoT and weather based smart irrigation system is developed. First, an efficient drip irrigation system which can automatically control the water supply to plants based on soil moisture conditions is developed. Next, this water efficient irrigation system is given IoT based communication capabilities to remotely monitor soil moisture conditions and to manually control water supply by a remote user. Further, temperature, humidity and rain drop sensors are integrated to the system and is upgraded to provide monitoring of these parameters by the remote user via internet. These weather parameters of the field are saved in real time in a remote database. Finally, a weather prediction algorithm is implemented to control the water supply according to the existing weather condition. The proposed smart irrigation system will provide an effective method to irrigate farmer's cultivation.
