3d printing a case for feather esp32 w/BME280 sensor?

Post by laserdog »

Super excited about the new feather lines with the integrated humidy/temp sensor.

I want to 3d print some cases for them (battery powered) and place them around the house (e.g. indoor sensor).

My searches on thingiverse hasn't found many matches, and I am wondering how best to design the case for sampling and airflow? (assuming lipo battery power)

I don't necessarily need a full case STL, more just interested in tips for laying it all out, and avoiding the heat from the sensor of skewing the readings.

Thanks for reading!

I'd lay it out with the board on-edge, and vents top and bottom. That will allow convective air flow over the surface of the board to minimize heat buildup inside the case.

Sounds good... By on edge you mean, lying upright on it's long edge, right?

Looking at the board... Am I dumb, or I can't even see where the BME280 sensor *is*?

I assume it is on "the top" of the board with everything else, but for the life of me I can't see where it is.

Yes, on the long edge. The BME280 is almost dead-center on the board. It is the small square metal can with the little hole in the top. Right between the QT connector and the esp32 module.
