Every industry asks different questions – baiond answers them in your words.
All industriesWe build the data journey for your case – let’s talk.
One data layer, seven functions, answers in plain language.
All functionsTwelve sensor families, every variant, and the ones we build for you.
All sensorsAir quality sensors tell you when a room needs fresh air, when fine dust or ozone outside passes a limit and when the wind is too strong to spray. They pay off in offices, schools, stores and on outdoor sites where people work, play or grow things.
Bad air is invisible until people feel it: tired heads in the afternoon meeting, customers leaving the upper floor early, a headache after the service. A CO₂ sensor shows how much used air is in a room, particulate and VOC sensors show what else is in it, and outdoors wind, ozone and pressure complete the picture.
Each sensor runs on battery and sends by radio to the baiond Gateway; the Space System places it in its room, so a reading always has a location. Before the board meeting in Conference Room 3 that means a clear answer: 1,180 ppm CO₂ against a target below 800 ppm, so ventilate for twelve minutes before it starts.
Pick the variant that fits the place. Whatever you choose, the readings arrive in the same platform and answer the same questions.
Carbon dioxide sensor
How much used air is in a room — the clearest sign that it is time to ventilate.
Measures the carbon dioxide concentration in the air. Indoors, rising CO₂ means many people and too little fresh air: concentration drops and rooms feel stuffy. Outdoors it helps track the environment around a site and feeds emissions reporting.
PM1, PM2.5, PM10
Fine dust, pollen and smoke in the air, split by particle size.
Counts fine particles in the air — dust, pollen, smoke, traffic pollution — and reports them by size class. The smaller the particles, the deeper they reach into the lungs. Used near building sites and busy roads, in schools and wherever limits have to be documented.
Volatile organic compounds
Gases from paints, cleaning agents, fuels and sprays — the air quality CO₂ does not show.
Detects volatile organic compounds released by materials and chemicals: new furniture, cleaning agents, fuels, fertilisers and pesticides. It shows spikes that affect people or plants and helps time spraying or ventilation.
O₂ sensor
The oxygen level in enclosed spaces where it can drop without anyone noticing.
Measures the share of oxygen in the air. Most relevant in enclosed spaces such as plant rooms, greenhouses, cellars or storage with controlled atmospheres, where a falling value is a safety issue. Also used in environmental and wildlife research.
O₃ sensor
Ground-level ozone on sunny days — a risk for people working outside and for plants.
Measures ozone, which forms near the ground on sunny days with traffic and industry nearby. High values strain people working outdoors and damage turf, vines and crops. Used for air-quality indices and long-term monitoring at the edge of cities and industrial areas.
The two base readings of any climate, in one outdoor or indoor unit.
Records air temperature and relative humidity together. Outdoors the pair feeds irrigation plans and turf care and shows weather changes early; indoors it completes the CO₂ reading into a full picture of the room climate.
Atmospheric pressure — falling values announce storms and rain hours ahead.
Tracks atmospheric pressure. A quick drop points to storms, wind and rain before they arrive, which helps plan maintenance, events and irrigation on outdoor sites. Usually combined with temperature and humidity in a weather station.
Anemometer and wind vane
How strong the wind blows and from where — for safe spraying, events and play.
Measures wind speed and direction. The data decides whether spraying drifts, whether sprinklers hit their target and whether play or an event on an exposed site is still safe. Usually mounted on a weather station.
AQI
Several pollutants combined into one index anyone can read at a glance.
Combines particulate matter, CO₂, VOC and ozone into one standard index. Visitors, pupils or staff do not need to know what ppm means — a single value or colour tells them whether the air is good. Common in public areas, schools and sports facilities.
Every variant at a glance, with the protocols the readings travel on.
| Variant | Measures | Typical use |
|---|---|---|
| CO₂ sensor | CO₂ in ppm | Meeting rooms, classrooms, churches, sales floors |
| Particulate matter sensor | PM1, PM2.5, PM10 in µg/m³ | Streets, building sites, schools, city districts |
| VOC sensor | Total VOC as index or ppb | Offices, workshops, fresh renovations, greenhouses |
| Oxygen sensor | Oxygen in % by volume | Plant rooms, cellars, greenhouses |
| Ozone sensor | Ozone in ppb or µg/m³ | City districts, vineyards, sports grounds |
| Temperature and humidity sensor | Air temperature in °C, humidity in % | Rooms, golf courses, sports turf |
| Barometric pressure sensor | Air pressure in hPa | Weather stations on large outdoor sites |
| Wind speed and direction sensor | Wind speed in m/s, direction in degrees | Golf courses, vineyards, stadiums, events |
| Air quality index sensor | Combined air quality index | Schools, public buildings, sports halls |

A question this sensor answers, the way baiond answers: readings, reasons, a recommendation and the source.
The sensor reports to the baiond Gateway, the Space System puts the reading in context (location, threshold, history), and the AI agent turns it into an answer.

No. The CO₂ concentration is currently elevated at 1,180 ppm, exceeding the target range for high cognitive performance (under 800 ppm). Temperature is fine at 23.4 °C.
Open the windows or activate ventilation for 12 minutes to bring CO₂ down to approximately 650 ppm before the meeting.

Understood. I keep watching HQ · Conference Room 3 and let you know if anything changes.
Where this sensor carries the answer.
A common guide is to ventilate once a room passes about 1,000 ppm; many buildings aim to stay below 800 ppm. You set the target per room, and baiond tells you when and where it is exceeded.
Rarely. CO₂ is a room reading: the full meeting room and the empty office next door can be far apart. One sensor per regularly used room gives answers you can act on.
Yes. baiond can show a simple index or traffic-light value per room or site on a screen or in reports, so people see at a glance whether the air is good.
baiond already uses regional weather data. A station on site adds what happens on your ground — wind on the exposed hole, the frost pocket, the gusts at the stand — which the nearest official station cannot see.
