Example calibration procedure for humidity sensor:
1) Place the ES-TH in a controlled-humidity environment along with an accurate humidity reference.
2) Set the humidity to some level toward the low end of the range, like 10-20%, and wait for it to stabilize.
3) Write down the humidity as indicated by the reference, and the humidity as indicated by the ES-TH.
4) Repeat the previous two steps, except set the range toward the high end, like 70-90%.
5) Enter the values that were written down in the appropriate settings:
event.sensor[x].humid[y].callowin
= <low indicated value>
event.sensor[x].humid[y].callowout
= <low reference value>
event.sensor[x].humid[y].calhighin
= <high indicated value>
event.sensor[x].humid[y].calhighout
= <high reference value>
For example, if the eventsensor 1 indicated 23% RH when the reference indicated 30% R, and the eventsensor
indicated 84% RH when the reference indicated 90% RH, then the following values should be entered:
event.sensor[1].humid[1].callowin
= 23
event.sensor[1].humid[1].callowout
= 30
event.sensor[1].humid[1].calhighin
= 84
event.sensor[1].humid[1].calhighout
= 90
A similar procedure is used for temperature calibration.
