Implementation of Smart Automatic Farm Irrigation of Fields Using Internet of Things

Abstract

Agriculture is the practice of farming followed from our ancestors. Over the decades farming technique has changed with the development of technology. Current farming techniques make work more simple and reduces man power. Though there are developments in farming techniques still farmers face more problems in producing 100% yield. The IoT technology has lend a hand to agriculture in the name of Internet Of Things. Internet of Things, a widely known branch of computer science has introduced sensible farming to every farmer’s neighborhood and also providing constructive inexperienced agriculture. These IoT can be helpful to farmers in many agricultural disasters like climate changes, improper cropping pattern, pandemics, over irrigation and inadequate knowledge on farming techniques. Our paper presents a way to one of the major issue faced by farmers the over irrigation by introducing automatic irrigation of  fields regularly with the help of IoT. The IoT makes use of moisture sensor and humidity sensor along with solenoid valve for providing automatic irrigation of fields whenever the moisture level in the soil goes under the fixed value. The whole process of automatic irrigation is carried out by photon (the microcontroller) and the moisture sensor. The photon which makes use of the in-built Wireless Fidelity (wifi) send the moisture level and humidity level frequently to any online platform or web services. These web services acts as user interface or controller for the farmers which allows them to control the devices remotely over the air.These platforms also stores the recorded data daily and provides as a database which can be used for future prediction. When the moisture level falls below the threshold level the photon sends signal to the solenoid valve through relay. Current moisture level and valve state are monitored through web services.
