I want to build a motorcycle alarm. I'm wondering if it's possible to send a sms wirelessly to my mobile phone when the bike is interrupted. If so, what modules do I need? Thanks. http://www.8051projects.net/forum-t10315.html 2008-12-01T23:42:53-08:00 say2paul Colin Mac wrote ...Hi, Arun.

Just so long as I know.You are right Colin, there are modules available in the market which can send SMS and even place a call. You can find them on google.Plus they can be easily interfaced with microcontrollers. http://www.8051projects.net/forum-t10315.html 2008-12-01T23:42:53-08:00 Colin Mac Excellent thanks http://www.8051projects.net/forum-t10315.html 2008-12-01T23:42:53-08:00 Arun Kumar V Hello Mac,are you very particular about sending SMS only when the bike is tampered, bcoz when you get SMS on your Mobile your are notified by a small beep/tone/alert.in emergencies like theft you need something like real ringing on your mobile, as if your bike it self is calling you for help !there are two ways of doing this job : Easy way and Fancy(hi-fi) way.both the ways need a Mobile phone probably GSM & a microFancy way :1) Mobile phone with easily accessible Serial port2) Micro3) Data bus cable4) good/fair knowledge of mobile AT commands5) lot of programming/debuggingEasy way (my way of doing it):1) any old, stupid,outdated,working Mobile phone with/without serial port2) micro3) ?????? tell me if you are interested in my (easy) way of doing the job Arun http://www.8051projects.net/forum-t10315.html 2008-12-01T23:42:53-08:00 Colin Mac Hi, Arun.

Those modems are expensive. http://www.8051projects.net/forum-t10315.html 2008-12-01T23:42:53-08:00 Arun Kumar V Huh-Ha, back to square one !Arun http://www.8051projects.net/forum-t10315.html 2008-12-01T23:42:53-08:00 Colin Mac Hi Arun. I'm looking at FBUS. It uses Tx and Rx like regular RS232 at 115,200 baud.Except I found some C code for a PIC and nokia 3220 and the person is using 9600 baud. Can you tell what he is doing from this zip of schematic and code attached? Is it Fbus? pic16f84.zip http://www.8051projects.net/forum-t10315.html 2008-12-01T23:42:53-08:00 Colin Mac Anyone. How do I connect micro to Nokia 3220 or 3510i? http://www.8051projects.net/forum-t10315.html 2008-12-01T23:42:53-08:00 Ajay thats why you always look for GSM modems when making these kind of projects. You get the modems or modules and use it as per your needs. no issue http://www.8051projects.net/forum-t10315.html 2008-12-01T23:42:53-08:00 say2paul Mobile phone will be fine until you are making project at your own, but when you want to launch it commercially, I think there must be some proprietary issue with Nokia or other mobile phone manufacturer.You must confirm it with Nokia people! http://www.8051projects.net/forum-t10315.html 2008-12-01T23:42:53-08:00 say2paul 1. GSM modems are designed to work for 24 hours 365 days continuously without any problem.2. GSM modems comes with RS-232 port, i.e. it is very easy to interface with uControllers.3. Few modems comes with open AT, so you can do even more with these modems!
