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.

Piezo-resistive · Bosch BME690

Barometric Pressure P

Precise enough to detect a door closing. Calm enough to draw weather trends over weeks.

Why it matters

Weather, altitude, storms — all in one number.

Pressure trends forecast weather days before an app does. Rapid drops can trigger headaches and arthritic pain in sensitive people. For sports and aviation enthusiasts, absolute pressure and density altitude matter for performance.

How Envora measures it

Built around Piezo-resistive · Bosch BME690.

A MEMS piezo-resistive sensor measures absolute atmospheric pressure. Envora post-processes to produce sea-level pressure using your altitude, plus a 24-hour trend line to spot incoming weather.

High ≤ 1050 hPa

Pressure is context, not risk. Watch the 3-hour trend rather than the absolute reading: a 3 hPa drop in three hours is weather-worthy and a common headache trigger for sensitive people.

< 980 hPa caution

Severe storm conditions. Sharp drops accompany strong winds and heavy rain.

— Met Office

980–1000 hPa note

Stormy / unsettled weather. Sensitive people may notice headaches when pressure drops fast.

— Met Office

1000–1015 hPa safe

Changeable / typical UK weather.

— Met Office

1015–1025 hPa safe

Settled, fair weather.

— Met Office

1025–1040 hPa note

High pressure. Clear skies, often cold in winter, hot in summer.

— Met Office

> 1040 hPa note

Anticyclone — very high pressure. In winter, often associated with smog or temperature inversions.

— Met Office

What to do

Practical steps, not panic.

  • Watch the 3-hour trend — a 3 hPa drop in three hours is weather-worthy.
  • If you get pressure-sensitive headaches, the alert threshold is yours to set.
  • Use the altitude offset in the app if your home is above 300 m to get correct sea-level readings.

Where this channel does its best work.

Mould & damp risk

Mould does not appear from nowhere. It is the visible end of months of sustained humidity your house has been trying to tell you about.

Outdoor air events

Wildfire smoke, urban traffic peaks, garden bonfires. The wrong ventilation strategy turns a bad outdoor hour into a bad indoor week.
