So, are these fried? If so, lesson learned 🙂
If the sensors are still reactive, within gas resistance range, and on the trend to stable values, most likely they are not fried 😉
Ozone is an oxidizing gas, thus based on the exposed concentrations it will increase the gas resistance of the sensor. Outdoor air is quite different in compounds and concentrations than typ. indoor air, and BSEC's IAQ outputs are optimized for indoor use-cases.
