Assembled and tested a more permanent prototype with soldered wire interconnections on the 74HC4052 mux/demux.
Two temperature & humidity sensors shown. Tested it with the outdoor 120 VAC-to-12VCD power system. Will likely connect the third for reading conditions between the hive body and the insulated enclosure tomorrow. The fourth sensor shed a through-hole connector while I was trying to desolder and remove the bulky header pins–will have to be replaced.
Also need to reprogram the operating software to use daily logs with the date in the file names to facilitate log management.
Hopefully I can get this in the box tomorrow morning before the outside temperatures drop back below freezing and/or it starts snowing. The next version should log temperature and humidity outside, between box and enclosure, and under the inner cover or close to the cluster of bees.
The all-foam enclosure stayed put during high winds yesterday, although it was left at an angle. I have a better design in mind, based on this experience.
