Hi,

Is there the humidity sensor to support wider temperature range for relative humidity sensor?

required range is from -30C.

Thanks.

The part supports operation between -40 and 125C. What sort of usable %RH measurement would you be expecting at -30C?

Hi Josh,

It's 0% to 50%.

Thanks.

David -

At -30C you are off the normal psychrometric chart, and it (the chart) really stops (for %RH) at 0F (-17.78C) - so what are you trying to measure / what is the application?
