GSM Alarm

Fresh from the tips line, [Pedro] sent in his GSM alarm. He combined a GSM phone, a motion sensor and BasicX24 controller board. If the detector trips during a set time period, the alarm sends SMS messages to the terminator, er whoever you want. He was kind enough to release the code, but I’d like to see this with a smaller micro-controller board to keep the cost/size down.

  1. you can automate mms and sms. which would be a better solution.

    a $0.98 8 pin pic chip and a little bit of coding and this could be easily done for far cheaper.

    Basic stuff here guys

  2. not an Original idea, I designed the basic principal of this as a Shed alarm in 04, and was in recipt of several accolades from the Police and court magistrates for the arrest and conviction of the ringleader of the theives/vandals that were terrorising our allotment site for years.
    I used an old Sagem phone and hardwired directly to the SEND key, and had a door microswitch as the trigger to send a text.
    I`v shared this idea on as many places as I can (I didn`t know about this place until recently).
    all you need is a phone that doesn`t go into stby and erase the number you have ready to send, and some simple soldering skills.
    I urge Everyone to arm themselves with these in Cars, Houses, Sheds, boats… etc.
    it May give these little ba$t@rds pause for thought if enough of them get caught! ;)
