ST Temp/Humidity Sensor Ranges

I have not been able to find the ranges (temp/humidity) this ST device has online. Anyone have this info? I’m curious if it will handle fridge/freezer temps. I am also curious if the signal will reach outside of a fridge or freezer. I am a bit surprised that I could not find these range numbers on ST site for the product.

Any info would be great, thanks.

Operating Temperature: 0° to 40°C
