This wouldn't be vulnerable to that, as the SMS is sent via a web-based API. You'd have to block the Arduino's wifi/ethernet connection.

This isn't sending SMS over the radio network, it's hitting TelAPI over (presumably) the land line. A jammer would prevent the reception of the SMS at the site, which wouldn't harm this application because the whole point is that the owner is not present and needs an alarm.
It is, however, vulnerable to the outrageous latency problems (minutes, often) the unofficial messaging gateways have. I send my wife texts to her company blackberry because it's convenient, but ultimately had to duplicate them to her gmail address to ensure that she got them fast enough.

You're right there about the jammer. But in testing, it hasn't taken more than 20 seconds so far.

#15So what's the total cost?
- What's the cheapest Arduino board that would work with this sensor? Wouldn't it be cheaper to get a Raspberry Pi?
- How much is the power supply?
- It would also be cool if there was a way to send SMS over the regular wireless, like with one of those cheap emergency cell phone plans. That would make it a really nice alarm, no need for the internet, and it can work off a PSU even if burglars shut down the power/internet.

#16Really cool. It reminds me of a project my brother-in-law did to receive an SMS when the Ph levels in his salt water aquarium change.

I don't think the meth addicts burglarizing my neighborhood are that sophisticated. ;-)

#18Both an Elk M1: http://www.elkproducts.com/product-catalog/m1-gold-cross-pla... and a HAI Omni:http://www.homeauto.com/Products/HAISystems/OmniPro2/omnipro... can do this via email and can call your cell phone and speak the alarm to you and are UL listed fire/burglar system as well as fully programmable automation controllers.
They cost significantly more (about as much as a decent PC) but I would not trust my property or life to anything less honestly. My Omni has been running without reboot for years and does security/fire/hvac/irrigation/lighting/garage door control and has an iPhone app for control.

He shows it on a teensy, which if you're decent with a soldering iron can be done for as little as $16 + shipping. power supply is usb so no extra cost there. not sure how well talking to a phone would do directly but worth checking into.

You can get the cheapest Arduino you can find. About $50 total probably.
I would love to see this on a Raspberry Pi, but you will likely have to do some 3v3 to 5v translation or use the upcoming Gertboard.
