I'm a software engineer by trade... so I decided to make my own digital hygrometer for my build effort. Long story short, I got my sensor circuit working and a short program to read the relative humidity. Now I needed to calibrate it. I did a search and found a method that is supposed to work. I'm curious if you guys have ever heard of it. 1 Put salt in the lid of a milk jug. 2 Put a few drops of water in the salt. Just enough for it to look like wet sand. 3 Put top and hygrometer into a baggie 4 Seal baggie at let it set for 6-8 hours (6-8 is the only variation in the story I've found) 5 After wait, hygrometer should read 75% humidity. If not then calibrate acccordingly. You guys ever heard of this? and if so, WHY does it work? I work in true/false all day long. How on Earth is it garaunteed to be 75% in that baggie? |
