keyword=Exit window temperature
The exit window thermalcouple signal is very noisy (huge AC component.)
So in order to try to reduce the noise, it has been sampled 10 times a
second and then averaged every 200 samples. There is still a few degrees
jitter in this averaged signal. I have been experimenting with other
averaging schemes in the last hour or so, which is why the signal has
been dropping out. I couldn't get anything else to work, so I just ended
up changing the average window to 400 samples (40 seconds.)
For fun, look at these temperatures over a day. They both fluctuate by 2
degrees or so with a 4 hour period. Perhaps the AC cycle.
