Parts and Pieces

Most of the parts and pieces were custom made using a an Ultimaker 3D printer. The printer uses plastic, which worked well to make the prototypes. The pieces were designed in Rhino. 

Controls Housing

 This piece houses the LCD screen, Elegoo UNO R3, and the Breadboard. 

Sensor Housing

This piece houses the DHT 11 sensor that goes inside the box. The sensor is inserted and then a piece of foam insulation is placed to keep the sensor in place and reduce thermal bridging. 

Plugs

The plugs seal the holes at the back of the box that allow for pressure differential. They are used for the first part of the experiment.
