 It is the SHT41 Temperature and Humidity Trinkie as a quick easy monitoring solution, and you can see here this just slides right in, and that's a thick enough board that it actually stays in there quite nicely. Here you can see every two seconds I have it logging the temperature in both Celsius and Fahrenheit, so it's about 78 degrees in here right now, and humidity is at about 29%. I can probably skew that a bit either by just touching the sensor, that'll probably warm it up a bit. Oh, it's cooling it. I'm cooler than the air. You can see the humidity jumped up there just because of some perspiration on my finger, or if I blow on it. So if we give it a little warm, hot breath there, we got it up to 83 degrees and about 80% humidity. The SHT41 Temperature and Humidity Trinkie.
