Sense Hat temperature reading -200 degrees?

[PerryJapanTenchi]

Good afternoon. I've been using the sense hat since January 2016. The humidity readings have good. Beginning November 18 11:42 the humidity reading consistently returns 138.3. There were some variations, now consistently returns 138.3. The readings (temp, pressure) are ok. I've been logging the humidity, temperature, pressure since January 2016 every 15 minutes. I don't understand why the humidity reading is now stuck on 138.3%. Is the humidity sensor bad? Thank you.

Just encountered the same thing in my PiNet middle school lab. I have 16 installed Pi3's, all with SenseHats. Temp readings are everywhere from 320C to -45C on different Pi's.

I bought these last spring, but this is the first time I've played with the temp sensors. I'm hoping that I can get these replaced.....

Unfortunate, since it's an amazing HAT with so much possibility. This, however, will negate its usefulness for data collection and visualization.
