Overview of the eleven measurements
Carbon Dioxide ppm The breath signal. How fresh is the air you are in? Carbon Monoxide ppm Low-level exposure, tracked over time. Particulate Matter µg/m³ See what you breathe. Down to one micrometre. Temperature & Humidity °C · %RH Comfort is a range, not a number. Barometric Pressure hPa Weather, altitude, storms — all in one number. VOC & IAQ Index index Every gas. Every particle. One honest score. Sound Level dBA The ambient floor, measured — never recorded. Ambient Light lx Your circadian signal, measured.
For your space
All solutions
 Home Kitchens, bedrooms, nurseries, basements. Envora shows you what you breathe — and tells you how to fix it, usually for free. Office & Co-work CO₂ is the single strongest environmental lever on office productivity — and the cheapest to fix. Envora gives facilities teams and founders the number to argue with. CO₂ and indoor air quality monitoring for schools Classroom CO₂ and indoor air quality evidence for better ventilation decisions, measurable cognitive lift, and the data trail governors and parents want. Labs & Clinics Envora One is precise enough for laboratories, clinics and regulated spaces, and comes with a signed calibration certificate per device ID. Studios & Gyms Hot yoga, spin, HIIT and small studios generate extreme humidity and CO₂ loads. Envora tells you how your ventilation is holding up — live, per-room, per-class. Podcasts & Studios Envora flags the HVAC hum, the fridge compressor, the neighbour's drill — and the concentration drift that flattens your delivery — before the tape picks any of it up. Landlords & Letting Continuous, timestamped indoor air quality records for every unit you manage — so damp disputes end in data, not arguments.
