Review on Adafruit Si7021 Temperature Humidity Breakout by Shawn Reiter

I've bought many temperature sensors over the years and this one is probably the most reliable of them all. I needed a good humidity sensor that I could put in my dry box where I keep my 3D printing filaments. I wrote a simple program for my ESP to act as a web server so I can easily get readings from anywhere I have internet access. I will probably write new code to transfer data to the cloud hosting service when I have time. But in general this sensor is very accurate and fast, just what I needed.
