Is aluminium lose its electrical conductivity when it is oxidised ? Answered
I have a soil moisture probe that is generally use for gardening projects. So I read some articles that tell about oxidation of this probes in a week. I wanna make soil moisture sensors that I can use it in my experiments and you know inexpensiveness is important rule of DIY :). I planned to use aluminium plates as resesitive soil moisture sensor but I have still some doubt that oxidation of aluminium affects to conductivity or not ?
I will use the sensors for a year or at least 7-8 months. So I worry that couldn't measure soil moisture properly.
