Welcome to op5 tech news & blog


On this space we at op5 Tech will write about things that we encounter in our day-to-day work and it will of course be most about IT monitoring. But we will also write about interesting customer installations, what's on the Internets or whatever that we think might be of interest to our readers.
Happy reading!

We at op5 can sell you a temp probe that will cost quite a lot if you would like to use it at home. One way to monitor temperatures is by using TellStick as I talked about in my earlier blog. Another way to do this is via Arduino, a open-source micro controller board, a ethernet port and a temperature probe.
