A Survey on Efficient Internet of Things Based Techniques for Efficient Irrigation and Water Usage

India is the second populous country in the world. The major occupation of Indian people is agriculture but majority of Indian crops will be dependent on the monsoon. With the decrease in rainfall, farmers have to use other alternate means of freshwater for the crops. This increase in demand and unsupervised usage of the available freshwater has led to water shortage. To address this issue an efficient water management and prediction techniques need to be implemented by using the ever-augmenting technologies like (IoT), which has progressed in recent years as an effective and cost-efficient substitute to conventional computing techniques. The need to design a dependable assessment and innovative mechanism needs to be designed. - A system that is capable to calculate, monitor and predict an efficient usage pattern to reduce water wastage and avoid subsequent crop loss. This paper surveys the techniques and areas that have to be considered for developing an IoT based agriculture system.
