Case for NodeMCU and DHT22 to fix heat issue

thingiverse

A bespoke enclosure for an NoteMCU with integrated DHT22 humidity sensor, designed specifically for wall mounting. The primary objective of this design was to address a critical issue plaguing other enclosures: thermal interference. The NodeMCU's heat output consistently distorted readings from the DHT22 when both components were housed within the same enclosure. Simply switching the NoteMCU into power-saving mode did not resolve this problem. To rectify this issue, my design incorporates two independent air ducts and a dedicated heat shield to effectively isolate the NodeMCU from the DHT22. It's worth noting that this design is predicated on the NodeMCU v0.9 due to its relevance at the time of creation, which was specifically commissioned by a friend who possessed an assortment of these older units. For optimal results, this enclosure can be printed without support when positioned as illustrated. The thickness of both top and bottom layers does not significantly impact print quality; however, it does influence the amount of solid infill generated. For increased efficiency, consider adding an extra perimeter while minimizing top and bottom layer thickness to expedite printing by reducing unnecessary solid infill under sloping areas.
