Review on 🌡️ SHT31 D Temperature and Humidity Breakout Weather Sensor: Accurate Climate Monitoring Solution by Ray Cole

The humidity seems pretty accurate, but the temperature is off by more than 15°F. 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/thermally isolated from the PCB. 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.
