    Good day all.

    First, let wish everybody Merry Christmas and New year! All the best.

    Been a while since my last login here. I'm looking for device, which will have SIM (phone card) installed, and will call a number once "activation" signal is received.

    I'm currently using a mobile phone, with 2 wires soldered to any button , and have assigned "speed dial" to this button. So when relay is activated, phone calls a number.

    However, I've heard that there is a complete module, where you can have multiple input signals and 3-4 activation numbers.

    Will appreciate if anyone can direct me to manufacturer/seller.

    Are you a mad bomber? What would be the purpose of this?

    Wrong perception...if you think a bit deep into it, I need a reverse action.

    I'm looking for a decice , which will call the number on the activation of relay (in this instance, PIR motion detector), not the phone call controlling any relay (which could be taken as remote control of some sort of device)

    regards,

    J

    Alarm systems with cellular dial ability are available, is this what you are seeking?

    Yes,

    That will help too. Hope they are not too complex, to separate the "cellular" part from rest.

    I'd prefer to build my own circuit, and plug in the "cellular" part.


    I'll appreciate if you can send me any link to product/brand name

    Alarm companies use Cell Modems. Some older Cell phones with serial ports can be integrated with microcontrollers using AT commands for a DIY cell modem.
