bme280 self-heating issue #49
Description
it usually shows 3-5C above ambient temp; part of it is a self-heating mentioned by the data sheet, since it has no external sensor, and the other part - heat radiated by esp32.
self-heating can be probably reduced by doing less frequent reads (forced mode + read every 5 min or so).
new PCB must be designed in a way to move sensor away from the chip.
