Description

As with the original remix, the case is split into 3 parts for easier printing and assembling.
8 heat set inserts and 8 m3x8 screws. Heat set inserts are to be inserted into the middle part on both sides.

Note: according to the handling manual for the S88, the following apply. Disregard the below at your own risk: 

  • OBA shall not be subjected to any force
  • No gluing or molding on OBA
  • Minimum of 1mm rear to fixed mount, 1.5mm minimum distance from particle filter to cover/PCB
  • Minimum of 1mm edges to housing/cover/PCB

Given the above, my implementation floats both sensors via the power and data wires glued to the support structures; not suitable to high temperature/vibrational environments.

Differences of the remix compared to the original

I modified the remix model:

  • Enlarging the housing to accommodate a Freenove ESP32-WROOM module
  • Extruded retainers for the module pins
  • Modified the two side housing areas to take:
    • Adafruit Sensirion SHT31-D - Temperature and Humidity Sensor
    • Senseair S88 CO2 Sensor
  • Modified the Deckel opening in height to center the USB port, and slightly enlarged it to allow passage of an Ikea SITTBRUNN USB-C cable connector
