Our community has rated this post as helpful. If you agree, why not thank

Be careful with these cheap sensors. Last time I checked none of them were accurate in the CO2, air quality, etc departments. Look at youtube reviews, they expose crappy sensore. There is a reason why the others are $150+. Or know what you pay for.

If you pass gas on it after a meal at Taco Bell, do the readings change?
