Review on ๐ŸŒก๏ธ SHT31 D Temperature and Humidity Breakout Weather Sensor: Accurate Climate Monitoring Solution by Shawn Reiter

Revainrating 4 out of 5

I have a fool The accuracy here is terrible

The humidity seems pretty accurate, but the temperature is off by more than 15ยฐF. Tried with several Arduino libraries. It was very easy to get readings in all cases, but the temperature readings are practically useless. It looks like terrible self-heating. When the unit is first turned on, the temperatures are accurate and then steadily increase to compensate for 15+*F higher than the room actually is. UPDATE: It turns out that this device just isn't very well insulated/temperature sealed from the circuit board. It even conducts a tiny amount of heat given off by your Arduino motherboard or any other board, even if you use an inch or so of wire to separate them. When I switched to a wire about 6 inches long, the readings became very accurate. Nice sensor, but you can't connect it directly to your design board. It should be fairly separate. Increased the star rating but left 5 stars for it. I've seen other boards where they're really isolated by design.

Pros
  • Industrial & Scientific
Cons
  • Unsafe
