Need help with burglar alarm for a model house. - Page 2 - Electronic Circuits Projects Diagrams Free

rancid rock · 12th March 2006, 06:18 AM

i am more concered with with complexity than size, but my base for my model house will be around 450mm * 450mm, the house will be ontop of that leaving room for the sensors in the front of the house.......i am wanting to know what is alot less complicated than a keypad? (i can have my keypad or whateva i decide on doing outside of the model house, so size isnt all important, just preferable to be small).

thx :wink:

srry if it came off wrong but 'exactly' i want something the activate and deactivate an alarm system that is less complicated than a keypad.

thx again :wink:

AFAIK, other than a hidden switch , a keypad is the least complicated .
i don't know what u will require :roll:

awww...but the keypad programming is so tedious and annoying, hidden switch u say?, where would one of these be hidden???

do u plan to use a micro for the locking system.?
then a what about a coded IR Tx + Rx system ?

rancid rock · 12th March 2006, 10:24 AM

hmmm....the only constraints other than what i hav explained is it has to be run off a microcontroller.

rancid rock · 13th March 2006, 01:15 AM

akg, would a IR Tx and Rx system be hard to do??? i know very little about them.

rancid rock · 13th March 2006, 02:29 AM

and dont say google it........cause i did!......

if u understood what i meant , then i would refer u to take a look at nigel's tutorial, especialy on IR system.

where is nigel's tutorial? link plz.....

You could make it respond to multiple codes, so that you can hand out different codes to different realtors. It logs the codes. The purpose being that if someone hands their code out and an incident occurs, you know which realtor is responsible.

You could also do an SMS link, you call the owner and they'll send a message to unlock the door for you. Of course the owner must be available (cell phones are a good thing). You could set it up so that the owner can send a message that it should unlock for a limited period of time too, basically you set up an appointment to show up there between 2 and 4pm and he sets it so "159" will unlock it during that period.

In fact you don't necessarily need a communication link. It could keep time and all codes are calculated from a seed. So he could type the time they want into his computer and say, "ok, 856 will open it between 2 and 4pm".

understand the concept and modify it for this system.

Eh Rancid Rock,
Check out that sms controller project that siliconchip did awhile ago. It would be easy to hide the controller board and wire up the doors via relays then you could simply send an sms message from your phone to open any door you've hooked up. This kit is avaliable from jaycar off memory and sounds just the thing for your project.

Cheers Bryan
