I want a small data logger with only
the pure MDBT42Q, a CR2032 (or similar) and the built-in temperature sensor.
Is this sensor good enough for recording the room temperature every 15 min
(for about 7-14 days) without requiring particularly high precision, but it should not drift too much when the voltage drops.
Does the chip heat up too much to record the room temperature?
(Maybe even secured under glue)?
Or do I need something like a DS1820
Has the board enough power to drive this sensor?
