I think, they need some circuit which can send SMS. My research says, they need some signal controller (SC) which send ON/OFF signal to keyboard of mobile. And some unique pattern on ON/OFF signals. So when somebody give a misscall to the old mobile, automatically SC will be activated. Once the SC is activated, SC send ON/OFF patten to keyboard of mobile, something like "Menu" + "Right Arrow" + "Right Arrow" + "Enter" + "O" + "N" + "Send" using this sequence, unique sms will be send to predefined number.
The alternate way is to play with AT Command. Once Circuit is activated, it read last miss call number and then it send sms back with status. I found http://www.serasidis.gr/circuits/smscontrol/smscontroller.htm But it do not meet exactly with the requirement ! Also, there is 3rd way to accomplish the task !! When user give a call to the mobile, remote mobile can reject the call (receive call) or attend the call (pickup) or not attend the call (miss-call). using this, user can differentiate that whether motor on ON or not.. ON = busy rigntone.. user cut the phone.. OFF = user you are calling not available ... In thiscase, all we need one wire from keyboard !! @Arshpreet - How much Respberry thing will cost ? 2014-08-18 12:30 GMT+05:30 arshpreet singh <[email protected]>: > > On 18 Aug 2014 11:54, "Narendra Sisodiya" <[email protected]> > wrote: > > > I want to know possible solution where "Kisan" should be able to control > >their motor as well as they should be know the status of motor (ie On or > Off) > > IMO Respberry pi can help us.
