/Projects/GSM call alarm

GSM call alarm is a device that will call a destination number via Siemens or Ericsson GSM phone (19200 bps RS232). 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.

In project file for download, you will find a JPG image that describes how to program the number you whish to be called when alarm occures. I hope you will find some use for this device, as I did - for my car.

Upisuje se umjesto tog broja. Prije nego sto kliknes "BURN" ili "Program" dugme na IC-Prog-u, iskljuci onu kvaku "CP" i onda ce moci da verifikuje.

Ja imam jedan problem sa programiranjem PIC-a. Kada ucitam HEX fajl i izvrsim verifikaciju dobijem odgovor da je problem u adresi verify fail at adres 0000h! i to mi se dogadja sa *,hex fajlom sa sms alarmom i sa gsm alarmom. Koristim allPic i ic-prog 105c.. I jos jedno pitanje da li se broj upisuje umesto broja +38762xxx ili u nastavku probao sam i jedno i drugo i ništa. Hvala

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!

How much is = also add letter "a" at the end of your result! Eg.: 7a
