- Can we expect meaningful readings from an ambient temperature sensor right next to a 320°C hotplate in a tiny package?
- Does that even work at least halfway accurately?
See pages 8-9 of the datasheet.
datasheet page 19
Make sure your solder doesn't melt.
How am I supposed to understand that?
datasheet page 19 points to warmup period (ca. 30 ms) before reading the sensor.
The melting point of solder is just below 200°C. At 320°C your sensor may fall off the PCB, assuming it can handle the temperature in the first place (it's almost certainly out of spec).
Operational range: min -40°C, max 85°C
BME680 data sheet, page 8:So 320°C is indeed out of spec, as I expected already.
