LUXAFORMeteo – Indoor Air Quality and Microclimate Monitor For Home and Office – Measure CO2, Humidity, Temperature, Noise and Lighting

I bought this to monitor CO2 in my bedroomGreat size and interface but the CO2 accuracy is terrible. I compared it to an expensive CO2 monitor that is calibrated and highly accurate and the Luzafor Meteo is out by a factor of 50%.Currently my accurate monitor says 810ppm CO2. I have a couple of other less accurate monitors and they agree quite closely. The Meteo currently says 1229ppm CO2. 50% higher than the real reading!Total waste of time and I strongly recommend no one purchase this.
