Agriculture and farming techniques are linked with Internet of things (IoT) and automation, to make the whole processes much more effective and efficient. IoT is the most evolving, promising technology which enables agricultural farms to automatically maintain and monitor with less human participation. The SMART irrigation system is an emerging technique that automates irrigation systems and allows farmers to meet their demand with a new adopted technique which conserves the water for irrigation process. Smart Irrigation systems save water, time and money. Automated irrigation systems are essential for conservation of water as well as have a vital role in minimizing water usage.

The SMART irrigation system includes data acquisition (sensor), irrigation control, wireless communication, data processing and fault detection. Each of these components can be used in IoT devices. Uses of IoT technology in the field, the workload and management have become easier because with the use of sensors, one can easily detect the temperature, humidity, and quality of the soil. It also helps in automating the process of irrigation based on the soil condition. IoT information on water requirements in rice fields can be monitored at a distance, making it easier for farmers to care for their rice fields and reducing problems in the irrigation of rice fields. Agriculture in the majority of poor nations, like Bangladesh, depends heavily on conventional energy sources to power the motors and pumps, which causes our land to become a desert because the irrigated fields lack access to power consumption. IoT based operating, monitoring and controlling system for temperature, humidity and soil moisture in land area with effective and efficient utilization of renewable resources which is abundantly available such as solar energy. Solar powered smart irrigation system is designed using IoE environment. The irrigation system predicts the expected water level values, weather forecasts, humidity, temperature, and irrigation data. Sensory systems help farmers better understand their crops and reduced the environmental impacts and conserve resources. Through these advanced systems effective soil and weather monitoring takes place along with efficient water management.
