Accurate temperature/humidity measurement over a wide working range,  fitted  in  a  small-sized  housing  and  high  flexibility  have been the main goals for the development of the FHT23 series.

Calibration data and other relevant functions like linearization or temperature compensation are stored in the probe.

The  humidity  and   temperature  measurement  are  available  as analogue outputs (0-5/10V or 4-20mA).
