We had some requests for a 1U sensor that did more than just read the temperature in one spot in the chassis and after looking at what was available we decided to make our own.
Featuring two temperature sensors with 1M probes and an ambient temperature+humidity sensor, it’s a great way of measuring intake/exhaust temperatures as well as the internal rack temperature with the added bonus of humidity. At 1U it takes up a minimal amount of rack space and the probes are quite thin, making it practical to route them around your rack.
Let us know if you want one included with your next server build!
