It's difficult to say what is the absolute truth. My personal feeling is that Sensirion is closer to the real value. The following graphs have data for one week. I am planning to buy Vaisala sensor (less than 400€) in order to have reliable values in case SHT31 does not work well. I started with HIH-4000 sensors more than ten years ago but they also lasted only one winter season.
