At the present era, the farmers have been using irrigationtechnique in India through the manual control in which thefarmers irrigate the land at the regular intervals. This processsometimes consumes more water or sometimes the waterreaches late due to which the crops get dried. This problem canbe perfectly rectified if we use microcontroller and GSM basedautomated irrigation system in which the irrigation will takeplace only when there will be intense requirement of water.

In the present world of wireless technology everything is
going to be digital and wireless, and the cell phone is the
key player in wireless technology today. Today theworking is going on how to develop remote devices
without the presence of man and to reduce to the time
factor and labor and by using it we can control any
electronic devices through a cell phone, with one SMS.

In Earlier days, farmers manually irrigate the
land at regular intervals.D
ue to this there ismore consumption of time and labor. This
process sometimes consumes more water or
sometimes the water reaches the land late.
Due to which the crops get dried.

To rectify this problem, we use microcontroller
and GSM based automated irrigation system.
Here we use the wireless technology where cellphone is the key player.
Thus we can reduce the time factor and labor
i.e,the motor will turn on with one SMS.

It has been developed by integrating features of all
the hardware components used. Presence of every
module has been reasoned out and placed
carefully thus contributing to the best working of
the unit. Secondly, using highly advanced ICs
and with the help of growing technology the
project has been successfully implemented.

By using some extra devices we can check
the status of machines whether they are
working or not and also the part which is notworking properly (sensors). By adding extra
software, we can use our project for security
purposes.
