Hi friends,

small intro about my project: It's fully gsm based pump control, i'm using sim900a module , pic18f4520 controller, ds1307,etc
power supply details.
transformer 240v/12v-2A
gsm i/p is 4.13v,
we can turn on/off the pump by manually or by using gsm(call/sms),
motor will turn off , manually,using mobile phones(call/sms), dryrun pff,overload off,
