I measured relative humidity using HIH 4031-003 in collaboration with NI-9201. This sensor has 3 pins, namely (+) supply Voltage 5Volt, Voltage out (to channel 1 on NI-9201), and (-). I have problems with the output measurement results in the form of fluctuating voltage values such as noise. Is the wiring diagram that I made correct?
What is the solution to my problem?
Thank you.
