A small experiement where I attached a cheap USB temperature probe to a Omega Onion 2+ (kinda like a Pi device). I created a small program in Golang using the Prometheus client and obtained the readings from the USB device. I then pointed my Prometheus/Graphana instance running on my Kubernetes cluster to scrape and log the information. Quite overengineered if I have to say it myself, but I learned a lot and that was the point!
cool, what do you think the fluctuations are from after sun rise around 7am? is the sensor quite close to your computer, could fluctuations be from the computer fan or something else?
