/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.

hello again! today replaced the program in the PIC what you sent me, and it's fixed the problem with the recalls. when the incoming call is cancelled after 40-50 secs it returns to alarm enabled state. here is some pictures, and test videos(read comments first!): http://angyalszarny.uw.hu/callalarm.jpg http://angyalszarny.uw.hu/callalarm2.jpg http://angyalszarny.uw.hu/test_1.MOV http://angyalszarny.uw.hu/test_5.MOV http://angyalszarny.uw.hu/tests_comments.txt regards, angelwing

I will send you new HEX to your E-mail. This one should work better for your phone... After testing, give us your results.

ei trax, the module is now working, but it didn't call the number.. is it my phone MC60? or the encoded number on the hex? because when i encode it on the ICprog, I copied its ASM instead of hex and paste it in the mplab.. because our pic programmer is supported only on mplab, the picstart plus. Do i messed up the programming? what can you advise? thanx trax

ARME is ON/OFF pin that needs to be activated in order to "Arm" the alarm (make it ready).
