So I just finished doing preliminary experiments for a soil temperature monitoring project and I'm looking to upscale the experiment.
My current experiment has 20 DS18B20 sensors hooked to an Arduino and placed inside some soil. To calibrate these, I used two point calibration (0deg C and 100deg C) by manually measuring the value that each sensor reads at 0degs C and 100degs C, and then hard coded these values in my program to calibrate them.
The result of my experiment was good and I would like to scale it by a factor of 200 - so 4,000 sensors. Calibrating 20 sensors took me half a day (as well as getting the individual addresses of each sensors) so maths tells me that I would need 100 days to calibrate all of the 4,000 sensors.
You obviously know my question... how on earth can I mass calibrate of all them?
