Relative Humidity (RH) is calculated based on saturated vapor pressure, which depends on temperature and atmospheric pressure. Unfortunately, the data Athar posted shows the relation between RH and the unit output voltage only at 25 degC. It is not clear on the datasheet (and on its web page either in English nor Japanese) that this unit applies temperature compensation by itself.
Ask to the company the data on another temperature. As this unit also outputs temperature signal as a thermistor resistance, you can compensate it if needed. Tsuneo |
