HDC2080EVM: HDC2080EVM

Part Number: HDC2080EVM

Hello team, 

Recently I have tested the HDC2080EVM, using the GUI. However, after a couple of tests, I have found out that the sensor humidity range is between 0% and around 80%. Once the humidity is above 80% the sensor measured values drop to 0 and once the humidity is a flat 0 the measured values start to increase. Is that a common problem, or something might be wrong with the sensor.

The first graph shows the problem with % above 80 and flat 0. The second is operating between 80% and 20%, with a good follow, but offset.

Best regards,

Petar
