The Bunnings wicks are a bit bulky. I might try re-lacing one with a bit less cotton. I did use a vacuum cleaner to suck a bit of air movement and the wet bulb dropped enough to reduce the Rh by 10% as expected. To measure soil moisture, the resistance of plaster-of-paris between a couple of metal plates 1cm apart is not bad. Jim VK7JH MMedit |

Not sure how accurate it is to measure the air humidity through measuring the soil humidity. But maybe that can be done also. Thanks for the suggestion. For the time being I will focus on repeating Jim's test (I found similar wick, we use it to light fireworks newyears eve). Volhout PicomiteVGA PETSCII ROBOTS |
