/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.

Check the connection with the phone. You probably didn't connect something right. This alarm module works fine, many people built it. You will need to try a bit harder!

You can try with WinPic it works 100\%.I've tried it and i assure you that works.You could find it on google and it's free. You should adjust com port, and that is

Every car alarm has one wire that is GND when alarm is armed, and it is VCC when alarm is not armed. You will find that wire in your car-alarm and connect it with GSM Call Alarm "ENABLE" input.
