Question

If a rehydration cycle isn’t a viable option, can the sensor’s on chip heater be used to recover the part from high readings as a result of contamination or high humidity exposure?

Answer

By using the heater’s maximum current setting, the sensor can partially recover but in general the heater does not get the temperature high enough for a full recovery.
