In my last post I talked about an issue my company had. We couldn't monitor our paging infrastructure from end-to-end and we couldn't find anybody selling anything that could. Before folks start yapping about pagers, you will see them in the healthcare sector for many more years to come when it comes to contacting a doctor for a life safety issue (cardiac arrest, etc) there is nothing currently sold that is as reliable and timely in the crowded RF world of a hospital.
I had built a prototype monitoring system using one of our pagers and an Arduino paired with a Windows Service. Well, it works and it works wonderfully so I was asked to build three more. Using multiple devices ensures we don't get false positives regarding a system outage due to the device or computer failing.
I've long been a fan of Adafruit and they were my first choice when I had my company order the parts needed to build out the rest of the monitoring devices. I leveraged the Arduino enclosure and the protoshield they sell and everything worked out wonderfully. I must say for a home-built gadget, they look pretty darn good and they perform wonderfully.
My apologizes for the quality of the pictures, had to use the cell....
