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.

About

We care about the air.

Envora Labs started with a simple observation — the air we breathe indoors is mostly invisible to us, and fixing it is usually free once you can see it.

Origin

From a noisy bedroom to a complete instrument.

Envora started with a monitor taped to a bedroom wall. Our founder could feel the morning fog but could not name the cause. A cheap CO₂ sensor showed it — 2,400 ppm by 4 AM, every night. A trickle vent fixed it in a weekend. Sleep improved. Focus returned.

The problem: existing monitors are either toys or instruments. Toys look fine and tell you nothing. Instruments measure properly and look like photocopier parts. Neither belongs on a kitchen shelf or a studio desk.

So we built Envora One — the comprehensive hardware we wanted ourselves. A machined chassis, a diffused halo, the best sensors in each class, and a dashboard that is straightforward to open. Priced so it can sit in every home and every office, not only the few.

Principles

How we work.

Measure, don't guess

The number ends the argument. Envora picks sensor tech that matches a reference instrument, not a toy.

Your data, always

We never sell, aggregate or monetise readings. Hardware is the business model.

Design is respect

A device you actually keep plugged in. Anodised aluminium. Diffused light. Considered typography.

Open over proprietary

REST and MQTT are first-party. The rest — Home Assistant, n8n, Grafana — connects through them. No cloud lock-in.

Repairable, not disposable

Replaceable sensor modules. Ten-year support horizon. We plan to still be around.

Evidence over marketing

Every claim is sourced. Every spec is real. Every calibration certificate ships with the device.
