+Comments:
+  * In green, the Wemos S2 Mini is just slotted there. It's a tight fit so it doesn't move. I placed it under the fan not to disturb airflow around the PM1006 sensor and avoid heating up the upper chamber. The aim is also not to influence the temperature measurement.
+  * In blue, I cut a piece of the plastic wall to let the cables pass.
+  * In red, I sticked the sensors on each side of the case as close as possible to the venting grill. I used 3M VHB double sided tape.
