Holistically, after the green revolution, India has been a global agricultural powerhouse of various crops and in present most of the farmers adopt the traditional irrigation methods but challenging task is in utilizing minimum water resource for more productivity per crop in diversified Indian environmental conditions. Water is a precious & scarce resource in many areas of the country due to traditional agricultural irrigation & industrial use. Hence, to limit water loss & wastage in farming it is important for maximum water application efficiency. Indeed, Systematic Irrigation System (SIS) for farming is need of hour and hence, attempt is made for development of SIS using computational device, and NodeMCU & Sensor technology are illustrated in this article. The SIS prototype has developed deploying ESP8266 Wi-Fi SoC development board and various sensors such as humidity, temperature, soil moisture, PIR & rain sensor. Graphic User Interface is developed in Blynk platform. This prototype has been tested in the laboratory successfully for application efficiency and has found good performance as expected.
