Weather based smart watering system using soil sensor and GSM

Abstract

In agriculture fields or lawns watering systems such as sprinklers or drip water wires are fitted to feed the plants to reduce human load. Normally sprinkler systems operate with respect to time, which means if we program it on 9 am it will be on even if rain occurs during that particular time. Since water is a precious resource we need to use it very carefully. Here we are proposing an idea of smart sprinkle system where human interaction and automation are combined. A soil sensor is used which gives the moisture content in the soil. If the moisture content is bellow particular level the sprinkler systems automatically gets on. We have also integrated current weather report, which can be used to augment the system. Based upon the weather data, watering the plants can be delayed for few days if there is rain prediction in the immediate days.
