/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.
In .rar file you will find JPG file that contains a description how to program the telephone number which this device will call upon alarm condition.

Connect it to a sensor you are planing on using. "It has 1 sensor input and another input
- state (stanje). If state input is = 0V than the device is "active" and it monitors
the sensor input. The device is deactivated when state pin is connected to Vcc (+). Sensor
input is triggered by 0V."

I don't know if it will work with A60 or A70, you must try it!

Thank you very much, it just stars work after adding the resistor of 4k7.The project is very
useful. Thanks a lot.

Actually, download the circuit from here http://www.elektronika.ba/666/tiny-gsm-alarm-system/
and see how GSM is connected to PIC (see the resistors and their values).

If the phone keeps loosing network coverage, try putting a resistor of 4k7 on GSM RX line!

hi, Trax. Thanks you for the great idea, but I have a problem with the device.
I make everything exactly like it you write it, but the problem is the phone coverage - the
telephone is searching for network cell at every 15 sec. If something hapenned during this
time, the phone /seimens C35i/ will not be ably to dial my nomber to notice me about alert. I
used the newest version of software /hex fail- dailing only once/. Any idea what can i do to
make it work?
