The temp offset controls on the SCD41 are slightly odd as they seem to kick in after start up and it gradually moves to right temp over a minute or two...RevKhttps://www.blogger.com/profile/12369263214193333422noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-45724042787576233412022-03-18T18:18:37.187+00:002022-03-18T18:18:37.187+00:00Not to detract from your worthwhile efforts to the...Not to detract from your worthwhile efforts to thermally isolate the sensor from the rest of the board, but if your circuit's average power consumption is quite stable and you have a fixed physical installation, then the error is just a simple constant offset (effectively it's power x thermal resistance to ambient) which is easy to calibrate out.Will Deanhttps://www.blogger.com/profile/15515078919433985452noreply@blogger.com
