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.
