Very timely post by Grafana Labs blog about temperature and humidity monitoring. It so happened that I had some Raspberry Pi lying around so I grabbed it, picked the cheap (sub 10€, c'mon, it's a bargain!) DHT22 sensor and started playing with it. My original idea was to replicate their setup, but later on I decided that this is an awesome opportunity to write some Go and, even better, my very first Prometheus exporter. So I did: hadret/dht22_exporter.
