/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.

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?

Hello! I cannot sell you boards because I don't have time to make them. You must do this yourself! In a few days I will publish new version of GSM alarm SMS/CALL in one device. When you connect your phone, LEDs will be OK.

You can not use Nokia with this (maybe you can, but I didn't try). You better find Siemens M35 or similar phone.
