/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.

Treba ti PIC programator. Najjednostavniji je ovaj: http://bit.ly/913Dj5

Posto ja imam par razlicitih sema za ovaj uredjaj promenio sam otpornik od 4k7 kojia je vrednost stavljena na prvoj pcb koji se nalazi odmah ispod pic mikrokontrolera sa 47k koji je obelezen na drugoj pcb i resio sam problem sa mrezom. Hvala TRAX

Problem sa gubljenjem mreze je rijesen sa dva-tri otpornika. Skini shemu ovog projekta: http://www.elektronika.ba/666/tiny-gsm-alarm-system/ i pogledaj kako je spojen mobitel na TX i RX. Vidices da imaju otpornici na tim linijama - takve iste dodaj u ovaj projekt i nece biti problema sa mrezom.

Jos jedna interesantna stvar koja se meni desava je ta da mi telefon povremeno izbacuje na ekranu NETWORK SEARCH pa opet pokazeda je u mrezi i tako na svakih 10 sekundi. Radi se o telefonu siemens me45 koji kada nije prikacen na alarm radi normalno,a i na modelu m35 se isto desava.

Koji hex je bolji,onaj ok gsm call hex, ili gsm call hex,ili neki treci provereni.Plasim se da nije neki bag u hex-u. Programiram ga sa GALEP 4, tako da mislim da nije do programatora.

Pre par dana pojavio mi se problem na gsm alarmu v1. Kada sam ga sklopio,nekoliko dana je dadio dobro posle cega je iskljucen i nije koriscen neko vreme. Posle nekoliko dana koriscenja pocelo je da mi se desava da alarm sam pozove kao da je aktiviran a nije. Primetio sam da su ti intervali izmedju tih laznih poziva prilicno tacni(oko 3 sata).To se desava i kad raskacim senzor sto znaci da je kvar u samom uredjaju. Posle reprogramiranja pic-a opet radi dobro neko vreme posle cega pocinje isti problem sa
