THS45 reference comparison: The SHT45 sensor used shows readings close to the SHT40, with slight differences in humidity.

We compared another set of commercial sensors with the SHT45 probe used in the THS45. Their results were very close, with a slight deviation in humidity readings (another commercial sensor showed even closer agreement). Overall, this performance may be difficult for most users to detect, but it could carry different significance in precision applications.
