AirCarto deploys an open network of IoT micro-sensors to continuously measure air quality. Indoor and outdoor sensors, open data, visualization tools — serving local authorities, businesses and citizens.
From the elected official steering their Smart City to the teacher equipping their classroom, AirCarto adapts its hardware and data to every need.
Map air quality across your territory, ground public policy in data, feed low-emission zones (LEZ).
Territory solutions →02One-off measurement campaigns or autonomous 4G fixed networks, data certified via AtmoSud.
B2B solutions →03Educational sensor kits, classroom air-confinement monitoring, build-your-own workshops.
Citizen solutions →From the certified 4G outdoor fixed sensor to the educational kit for schools. All open source, all interoperable with the AirCarto platform.
The reference sensor for professional measurement campaigns. High-precision NextPM probe, built-in 4G chip for a fully autonomous deployment, optional electrochemical probes (CO, NO₂, O₃, VOC). Mains powered or battery + solar panel for off-grid installation.
Measures CO₂, fine particulate matter (and VOCs as an option) with a large remote LED display. Designed in partnership with AtmoSud, deployed in schools and public buildings to manage ventilation in real time.
The citizen sensor par excellence: mount it on a balcony or windowsill, connect it to your home WiFi, and it publishes its measurements on the open map openairmap.fr. Become part of the network.
Continuous traffic counting by category — cars, trucks, motorbikes, bicycles, pedestrians — with on-device AI: no image ever leaves the unit, only numbers. Pair it with a NebuleAir Pro to correlate traffic, pollution and noise. Open data via API.
An acoustic module that plugs straight into the NebuleAir Pro: sound level in dB(A), Leq / L10 / L90 indicators, and real-time correlation with air-quality measurements. One station, two nuisances measured.
Touchscreen indoor air sensor measuring CO₂, fine particulate matter, temperature and humidity. Powered from the mains or by battery, it can run online or offline. Connected to WiFi, it sends its readings continuously to the AirCarto platform. Without a connection, it stores them locally, and the Cyan Sensor app retrieves them over Bluetooth for upload.
Monitor air confinement with a Raspberry Pi Pico 2W and an NDIR sensor. WiFi and cyanSensor mobile app.

Cyan Sensor is the companion app for your AirCarto sensors: add a sensor in moments, follow your measurements in real time, browse the history and adjust settings — straight from your phone.
AirCarto surrounds itself with leading partners to guarantee the metrological accuracy of its sensors and the durability of its field deployments.
Scientific partnerAtmoSud is the agency accredited by the French Ministry of Ecological Transition for the regulatory monitoring of air quality in the Sud region. Together we co-develop and validate all of our solutions against reference instruments (TEOM, FIDAS, gas analyzers) at their measurement stations.
Energy partnerRe Lion Factory remanufactures lithium-ion cells from electric mobility into reliable, resource-efficient and fully traceable batteries. This is the energy that powers our NebuleAir Pro and TrafiCount sensors when they run on autonomous solar power, anywhere in the country.
Les Petits LabosStudio · MarseilleA Marseille studio at the crossroads of art, design and new technologies. With them we co-develop and build our luminous sensors — including Neuma — which turn air quality into sensory, visual experiences in service of the ecological transition.

AirCitoyenAssociation · AwarenessAirCitoyen fosters lasting involvement of residents and professionals facing the nuisances of their environment — air, noise, odors, waste. Together we run citizen-awareness workshops on air-quality issues across territories.
aircitoyen.frAn open-source app run by AirCarto and AtmoSud. It aggregates data from professional stations and citizen micro-sensors via API.
AirCarto makes air-pollution measurement accessible to everyone. We design and build affordable IoT sensors, run workshops in schools, and support local authorities in deploying Smart City networks.
The source code of our sensors and platforms is public. The data we measure is freely accessible via OpenAirMap and our API. Citizen science, for real.
AirCarto was founded in Marseille in 2019 by Paul Vuarambon, after completing a Master of Science in Environmental Policy and Management at the University of Bristol. The starting point was a simple idea: build your own sensors.
Our Lab is where we assemble, test and repair our sensors, and where we prepare orders. It is equipped with 3D printers, a laser cutter and a soldering station.
Our servers are there too: we self-host our website and the sensor data.
