/Projekti/GSM call alarm

GSM call alarm je uređaj koji za zvanje odredišnog broja koristi Siemens ili Ericsson GSM telefon (19200 bauds RS232) i ima 1 senzorski ulaz i još jedan ulaz - stanje. Ukoliko je stanje = 0V tada je uređaj "aktivan" i prati stanje senzorskog ulaza. Uređaj se "deaktivira" otpajanjem on/off (stanje) ulaza sa mase (0V) ili spajanjem na + pol napajanja. Senzorski ulaz takođe reaguje na 0V.

Siemens C45 SHOULD work great! Steal it from your aunt :) And C25 should NOT work though.

Well, what I would really advise you to do is to get an old Siemens S25 or C35/M35 from eBay, or you can try that 4,91* crystal and get back with results :)

trax, may i ask again? There is no 5Mhz Crystal Oscillator available in my hometown.. i've search every electronic shops and no luck. they have only 4, 4.5, 4.9152, 8 , 10, and 16 Mhz Crystal Oscillators. Is it ok if I use 4.9152 Mhz with the Sony Ericsson phone? what can you advise? Thanx trax...

You should be able to use any model with internal modem such as Ericsson T28 for example. I really can't say, you must try it yourself!

If you want to use Ericsson phone instead of Siemens, you must use 5 MHz crystal instead of 10 MHz !
