System is Down Detector

If you work in a company that has a website, you know how important it is that the website always be up and running. That’s why you constantly see “99.99999% reliability!” all over the fancy server hosting sites. A website can’t make money if the system is down, so knowing when that happens and reacting quickly is super important. In this Instructable, we will use the LinkIT ONE board to make an alert system that will play a loud alert siren and send us a text message. This way no matter where we are, we can respond as fast as possible!

System is Down Detector

Since we’re harnessing a lot of the built-in power of the LinkIT ONE, we don’t need that many external supplies here. You can focus your gathering energy on a quality speaker to play our alarm through!

Speaker (headphones for testing is cool)
SIM Card (Pre-paid for deployment, borrow a friend’s for testing)
An Alarm MP3 File
A Website to check on!
