Review on Adafruit Si7021 Temperature Humidity Breakout by Troy Caldwell

I have purchased many temperature sensors over the years and this 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'll probably write new code to transfer data to a cloud hosting service when I find the time. But in general this sensor is very accurate and fast, just what I needed.
