Good water management practices will increase yields, improve crop quality, conserve water, save energy, decrease fertilizer requirements, and reduce nonpoint source pollution. Information is most critical to decide on exact amount of water required by a crop in a given climatic condition and for effective design and management of irrigation system, irrigation scheduling, etc
Sensor or transducer is defined as a device that receives energy from one system and transmit it to another, like physical variable into signal variable. one or more transmission systems. It provides a usable out put in response to specified input measured, which may be physical or mechanical quantity, property, or conditions.
It is imperative that the use of smart irrigation controllers can be an important option for improving water use efficiency. Use of sensors would ensure using right amount of water as appropriate to season, and climate and weather conditions. And scheduling can avoid over watering and excessive runoff. The main objective is to effectively and efficiently deliver services with usage of Information and Communication Technologies (ICTs) 11 in a minimum time. The pilot initiative whilst focusing on capacity building of various stakeholders in automatic measurement and use of real time data for decision making has research and innovation as integral elements.
