Hi,

I a using a humidity sensor to measure % humidity. I am facing a strange issue. The output of the humidity sensor (HIH 4000 -001; Honeywell) is getting fixed at 3.21 v. This is true even when the sensor measurement is done in a fixed humidity bath varying the humidity from 30 % to 70 %.

Has anyone got any ideas why this is happening.

Thanks,
Y. Li
