I'm looking for some help with temperature sensors. I have ordered sht31 for using it to control the temperature in my flat, but it is at least 2 °C off compared to my thermometers directly next to it. The sht31 is on a separate board, away from any heat source. I see others have really decent readings with them (even inside ±0.1°C) out of the box, and this is what I would expect from a sensor that is factory calibrated.
Do you have experience with these modules? Maybe mine is defective?
The SHT31 I have shows within 0.3° of a known accurate thermometer I use in HVAC work, how do you know your other thermometers are correct? You can offset the SHT31's reading in code if you don't trust it, post your code.
Hi,
I have compared the reading to two commercial thermometers, one in a weather station and one in a thermostate. They both show a similar value.
The code is just the adafruit sample for sht31. I'd like to avoid compensating the reading in the code, as these sensors should be factory calibrated.
