<t>Adding from 3D printing side: enclosure design matters for sensor longevity. Most of my outdoor BME280 builds use a Stevenson-screen-style multi-layer shade. Direct sunlight on a BME280 reads 5-8 degrees high, easy.<br/>

STL design tip: print the shade plates separately, glue together with ...

<t>Yung bass response sa 3D-printed enclosures, suffers ang ganda pag PLA. PETG slightly better for acoustics. For next iteration, try mo ng resonance damping, fill yung hollow space with sand or rubber granules between two skins.<br/>
