2-module DIY data logger with mini breadboards that swaps sensor modules easily

[TriplePointDesign]

The educational side of the project required different sensors for each lab, so we tweaked last years 2-part logger with 3D printed rails holding mini breadboards to provide this flexibility. The software has also been streamlined significantly and people shouldn't have too much trouble adding other sensors provided you stick to 1,2,4,8 or16 bytes/record and your modules don't pull more power than the coin cell can provide. The small form factor makes these easier to deploy, and the centrifuge tube is waterproof to several meters depth.
