IoT based irrigation system powered by solar energy

Irrigation of the agricultural sector is a major problem facing most farmers now a days. The problems associated with irriagation are over-irrigation, under-irrigation and manual labour. This paper presents a solar powered IoT(Internet od Things) based irrigation system for paddy fields to have an insightful approach for overcoming labour-intensive work and also to track the water management system. The mian aim is to diminish conventional methods of irrigation and support an intelligent way of watering the paddy fileds to conserve water and limit the over or under irriagation. The system is designed to be powered by a photovoltaic panel that enables smooth operation even during power cuts. The microcontroller is the heart of the device. Two microcontrollers are used to process the data, one of which is integrated with a humidity sensor, a temperature sensor and a humidity sensor. The inputs from these sensors are fed to the first microcontroller and these values are used to activate a solenoid valve that starts irrigation on the basis of soil moisture requirements. The output of the fisrt microcontroller is also fed to the second microcontroller unit, and the data is fed to the ThingSpeak platform, a cloud server powered by Mathworks. Thus, the irrigation cycle takes place without human intervention and can be tracked remotely from any part of the world.
