I thought I'd start a new thread, as the questions I have now and results I'm getting aren't related to the previous thread's title.
Now, the sensor is acting a little strangely and I wonder if anyone can shed some light.
The power supply is a 9V battery running a 5V regulator, actual supply voltage is 4.99V.
Last night, when attached to the 5V supply, the sensor output 3.98V. However, today, it is giving me a reading of 3.81V. That's far too big a change to 'blame' solely on barometric pressure change, so can anyone else think what's going on?
The sensor is temperature compensated. I've tried varying humidity levels, and using direct connections instead of a breadboard, but the readings do not change.
Thanks in advance,
Jon
