Abstract: In a country like India, whose economy is mainly based on
agriculture and the climatic conditions which are isotropic, we are still not
able to make full use of agricultural re-sources. The main reason is scarcity
of water. Another very important reason of this is due to un-planned use of
water as a result of which a significant amount of water goes into waste. In
the modern irrigation systems, the most significant advantage is that water is
supplied near the root zone of the plants. But the modern day drip irrigation
systems had not been automated. The problem incurred was the inability to adopt
labour for just switching on/off the valves and one more problem unnoticed was
closing of valves since it was a huge area. So, a low cost automation that is
user friendly for uneducated farmers was required to handle the system. This
situated can be improved if we use automatic controller based closed circuits
of Mini-sprinkler irrigation system in which the irrigation will take place
only when there will be intense requirement of water. The valves can be easily
automated by using controllers and solenoids. Automating farm or nursery
irrigation allows farmers to supply the right amount of water at the right
time, regardless of the availability of labour to turn valves on and off. So,
the implementation with a low cost processor will be able to sense the moisture
content of the soil level and irrigate the crops. Use of wireless module and
communication system like Zigbee would solve the problem of expensive cabling
involved. An alarm or any signal would indicate if the connection between the
sensors and the control system is lost to intimate the user so as to
troubleshoot the problem. Effective programming would further improve the case.
