Having the electronics secured and accessible on the evaporimeter is essential. The solution that we came up with is having a transparent jar that would screw on the evaporimeter’s pole attachment. Here is the updated design:
When turned to the underside, one can see the extruded base to accommodate the threads and the breadboard and battery compartments. The breadboard slot might be edited to have a slide in feature instead of having a little slot to hold it in. The battery slot is just fine. Here are some pictures of the assembled pole attachement with the jar:
The inside is not a smooth print because it prints on the support material, but we are more concerned about function of the inside piece and not the aesthetics.
A humidity/temperature sensor and a uSD card adapter are being added to the electronics. I prototyped these new electronics and wrote code for them. An intern here at the lab is integrating the code and new electronics into the current design.
