Perhaps Basic Stamp routine (code) for Sensirion sensor have an error.

Joe

Hi

How can I know if the Parallax routine
is working.

I ask this because I have four different sensors
from differents brands and the Parallax sensirion give me always
15% less humidity than the others.

Of course if I change the Basic Stamp routine (or code)
adding 15% to the routine the problem disappears.

But then, it seems that the problem is not the sensirion sensor,
it is the Parallax routine or code.

Do you have information ?

Thanks, Joe

I talked to the HVAC guy at work. He had the wet bulb humidity checker and I compared my sht11 to the controlled environment at work. It very close to the same. Under 3% difference. Now, that was around 40% so I didn't have the ability to test over the full scale.

I would see if you can find a HVAC guy and try your sensors out.

Good luck.
