I notice that in the BME680 and BME688 data sheets there is a statement that the gas heater is typically set to temperatures of 200 to 400 degrees C, but I can't find anywhere that specifies limits. I infer that the heater can be programmed as low as 100 degrees as there is an example of "a standard heater profile" in the BME688 data sheet (figure 1) that shows heater temperatures as low as 100 degrees.
The question is how low of a temperature can we set and how high of a temperature can we set without compromising the measurement or damaging the heater?
Thank you, Gary Marks
