A1007-GSM-Automatic Irrigation System

In the present era, lots of amounts of water is wasted in watering plants and gardening. It is a
challenge to maintain soil moisture for plants. Current watering system offers a scheduling
scheme as the solution, which might cause the soil to be too wet during the rainy seasons and too
dry during the drought season. Therefore an automatic plant irrigation system has to be designed
for the proper water supply for the plants. This project deals with an automatic plant irrigation
system which automatically senses the moisture content of the soil and decides whether irrigation
is needed or not and how much water is needed for soil. This system uses an Arduino nano. It
is programmed to sense the moisture content of the soil over a period of time. When the moisture
content is less than the limit which is predefined, it will start supplying the desired amount of
water till it reaches the limit. So when the soil is dry the pump will automatically water the fields
and when the soil is wet the pump will automatically switch off, thereby eradicating the need of
manpower and conserving the time.
