SMS controlled Wireless Irrigation System

Irrigating crops with the exactly right amount of water is a tedious task, especially when you have to walk a long distance to the irrigation pump in the middle of the night to check whether any problem (fish getting stuck in the intake and as a result the irrigation motor burning or jamming!) has occured

The prototype could do the following:


 * 1) Be remotely controlled via SMSs through a cellular GSM network.
 * 2) Send back ERROR messages to the operator, if the Miniature Circuit Breaker (MCB) was tripped due to electrical faults or motor jamming.
 * 3) Control loads of up to 15 amps.

Parts List:

Hardware Parts:


 * 1) 1x cheap/old/used GSM mobile phone with SMS feature(with charger)
 * 2) 1x Activated GSM SIM/micro-SIM card of your preffered provider
