Before the Internet of Things (IoT) has any impact on agricultural applications, most of the irrigation operations are still in the traditional model. That is, the farmland is irrigated with floodwater, which has low irrigation efficiency and wastes water seriously. Field monitoring is also needed, which requires a large amount of manpower and takes a long period of time. Long-term unscientific irrigation causes various agricultural planting problems such as soil structure damage and environmental pollution.

As the wireless network gradually expands the coverage and the IoT technologies develop rapidly, IoT is widely applied in agriculture. For example, by leveraging the IoT, irrigation is controlled through wireless communication. This new irrigation pattern is also well supported by the country.
