Device Container

The main purpose of the container is to hold all the hardware neatly together in a box that can be easily inserted into the soil of the plant being monitored.

To print and assemble your own device container, you will need:

  • M2.5 x 5mm Screws (14x)
  • M2.5 x 10mm Standoffs (4x)
  • Brown & Orange 3D printing filament (PLA)
  • Acrylic Plastic
  • Access to a Laser Cutter

Move 3D model

The 3D model above is interactive! Move the mouse over and left-click to change the perspective. Use the scroll wheel to zoom.

  • Window: the front of the container (made of acrylic) which makes it possible to see what is happening inside the container.
  • Case: the box where all the components are attached.
    • Top: opening for the USB-C cable to be inserted without having to remove the IoT-AVR Cellular Mini from the case (when recharging the battery for example).
    • Right: the right side has mounting points for the VEML7700 and the AHT20 sensors.
    • Left: the left side has a compartment for the battery.
    • Bottom: the bottom side has an opening to expose the Seesaw Soil Sensor to the soil.
  • Lid: slider that will allow you to open the container.

Assembly​

The assembly of the container is composed of 3D printing the case and the lid as well as then laser cutting the window.

  • STL files for 3D printing the case and the lid.
  • SVG file for laser cutting the window.

After downloading the STL files, you upload them into your slicing program of choice and then generate the files to be 3D printed. For the window, 3mm thickness acrylic should be used (it should have a dimension of 122.10mm x 39.60mm).

With all the parts made, the sensors should be screwed into their respective mounting spots. The AVR-IoT Cellular Mini should be assembled onto the backside of the window with standoffs.
