Watering is the most important cultural practice and most labour intensive task. Knowing when and how to water are two important aspects of watering process. To make the gardener works so easily, the automatic plant watering system is created. This system uses Arduino UNO board, it is programmed in such a way that it will sense the moisture level of the plants and supply the water if required. This type of system is often used for general plant care, as part of caring for small and large gardens This system can be effectively used from small gardens to a large crop field, thus also conserving water. We can implement the above prototypeusing sprinklers or drip emitters for effective irrigation. For largescaleimplementation, wecanusesolar panelstoconserve energy.
