Luftkvalitetsmätare med CO₂, temperatur och fukt

I manage a restaurant and indoor air quality affects both staff performance and guest comfort. Placed this in the kitchen and dining room. The kitchen reading helped us optimize our hood vent scheduling. The dining room reading informed our seating capacity strategy during high-demand periods.

I'm a teacher and my classroom air quality directly affects student focus. CO₂ rises dramatically with 30 kids in a small room. This monitor lets me know when to crack windows. Fewer 'afternoon slump' complaints since I started monitoring.

The app shows historical trends, not just current readings. Seeing how my bedroom CO₂ builds through the night or how humidity drops during winter heating season provides context that single readings can't. Trend data enables pattern recognition and better environmental management.

I set the alert to trigger at 1000ppm and sleep with my phone nearby. The few times the alarm has triggered at night I've opened the window and watched CO₂ drop back to safe levels within 15 minutes. Responsive air quality management during sleep.

The sensor readings are accurate — verified CO₂ against a professional meter and temperature against a calibrated thermometer, both within acceptable margin. My only wish is the display were slightly larger for across-room reading.
