## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works great!
  

*by T***T on Reviewed in the United States on August 10, 2017*

I am new to the world of Arduino, so at this point much of my coding has been modifying code that I download....gets me going and I have learned a lot. With that, I bought this and did just the same, but the only code I found was for displaying on a serial output screen on my laptop.... so I worked in code for a small 1" display and a traditional 16x2 shield.... took a bit of work on my part, but in the end I am able to display on either unit.It updates fast... I have a buffer of about 1000ms to keep the 2-point decimal from changing too rapidly...and now it is legible. It appears to be fairly accurate and what I wanted it for was to monitor the temperature and humidity in my basement and I am very happy with the results.

    Works but received the older version instead of the new one displayed in the pictures
  

*by R***T on Reviewed in the United States on September 29, 2021*

I expected to get the STEMMA QT current version of this board that is shown in the pictures and not the old header-only version.  Pics shouldn't show the new one if they aren't shipping that one.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    I now send my humidor stats to the web every hour.
  

*by S***R on Reviewed in the United States on March 16, 2016*

Works great and it was easy to configure on the Arduino.  Go to the Adafruit website, get the library and you can have it running in just a few minutes. I now send my humidor stats to the web every hour.
