Perfect indoor air quality thanks to formaldehyde sensor
ATMO is equipped with a factory-calibrated formaldehyde (HCHO) sensor. Electrochemical measurement technology is optimized to accurately detect low concentrations of HCHO, around WHO (World Health Organization) reference values. With particularly low cross-sensitivity to other VOCs, the sensor offers excellent detection performance for formaldehyde in indoor environments.
Formaldehyde is frequently present in indoor air, originating from certain coatings, floors and furniture. As this gas is highly reactive, it can react quickly and vigorously with other molecules. This makes it a potentially dangerous and carcinogenic compound.
ATMO measures formaldehyde concentrations in real time, to protect buildings and their occupants.
The product features Air 360° technology for ambient air analysis. Featuring large openings at the rear, this exclusive design allows gases to flow into the heart of the product for fast, reliable analysis.

The algorithm adjusts to available measurement data and quickly assesses air quality. It can analyze up to 9 pollutants simultaneously, measuring the concentration of each and prioritizing their hazardousness. In this way, appropriate measures can be taken to meet the specific conditions of your environment.

Efficient measurement of particulate matter
ATMO is equipped with an optical particulate matter (PM) sensor based on laser scattering. The product is able to measure and discriminate PM1, PM2.5 and PM10 concentrations in great detail. High-quality, durable components ensure accurate measurements from the very first use of the device, and throughout its service life of over ten years.
The finest airborne dusts and particles penetrate deep into the lungs, where they can cause inflammation and impair overall respiratory function.
ATMO will enable you to analyze the actual exposure of a living space to this atmospheric pollution and help you take the most appropriate remedial measures for the situation: ventilation, air filtration, air purifier, etc.
Monitors Indoor Air Quality and controls VOC emissions
ATMO is equipped with a Total Volatile Organic Compounds (TVOC) sensor based on highly sensitive MOx detection technology. This ensures reliable measurement even in damp and dusty environments.
Volatile Organic Compounds (VOCs) are highly volatile and easily dispersed in office or workshop atmospheres. VOCs can be harmful to health, and contribute to olfactory pollution.
ATMO helps you manage the ventilation of enclosed spaces and protect the health of occupants by limiting exposure to pollutants.
See CO2 levels at a glance!
ATMO measures CO2 levels every 10 minutes and visually alerts occupants when it’s time to change the indoor air.
Instantaneous measurement
Easy to operate thanks to the button on the front of the sensor. Useful for occupants or technicians (function can be disabled)
Regulatory compliance
Direct-reading sensor compliant with French standards for measuring CO2 concentration in indoor air
Indicator light
The Green / Orange / Red indicator changes with the CO2 level and alerts you when it's time to ventilate to renew the indoor air.
Complete environmental control
With its 3 dedicated sensors, ATMO optimizes lighting, energy, acoustic monitoring, space management and security, making it easy to automate your scenarios.
Ambience control
Measures noise and identifies noise pollution. Helps preserve a calm and peaceful environment
Detects presence
The motion sensor detects people up to 6 meters away. Useful for lighting, security or temperature control
Measures ambient light
The brightness sensor measures the amount of light in the room. Ideal for controlling lighting or adjusting temperature more quickly according to sunshine levels
Reliable, precise temperature and humidity analysis
To limit the risk of erroneous measurements, particular attention has been paid to integrating temperature and humidity sensors.
To guarantee optimum performance, ATMO has undergone rigorous testing and strict validation protocols in extreme operating conditions ranging from -20°C to +50°C and from 0 to 99% ambient humidity.

Frequently Asked Questions
Our experts answer your questions
NEXELEC sensors are capable of measuring different pollutants, depending on the model. Depending on the country and the environment, thresholds may vary.
Depending on WHO and ANSES regulations, thresholds may differ from one country to another.
The values set out below are valid for ERP (Etablissements Recevant du Public) in France.
Carbon Dioxide (CO2)
CO2 is a good indicator of Indoor Air Quality. If ppm levels are too high, ventilate as soon as possible.
Volatile organic compounds (VOCs)
These compounds are emitted by paints, glues and other solvents. If the concentration is too high, ventilate as soon as possible.
Fine Particles (PM)
PM are grouped into 3 categories: PM1, PM2.5 and PM10
Fine particles are often found in dust and smoke. Prolonged exposure presents a health risk. When the threshold is too high, open the windows to renew the indoor air.
Formaldehyde (HCHO)
Formaldehyde can be found in new furniture, cleaning products and so on. If your detector emits a Red LED, take action as soon as possible.
Carbon monoxide (CO)
If carbon monoxide levels reach excessive levels in a room, it presents a potentially fatal hazard. It’s crucial to detect the origins of CO in the environment, and to have all combustion appliances inspected, such as stoves, boilers, stoves and so on. If the threshold is too high, ventilate the room as much as possible.
NFC (Near Field Communication) is a magnetic field technology used to exchange data between a product and a smartphone.
To configure the product, simply :

A presence detector is a device that detects the presence of people in a given area for a defined period of time. NEXELEC presence sensors are designed to react quickly to movements and provide precise data on the actual occupancy level of spaces.
Generally speaking, at 80 dB and above, the danger threshold is considered to have been reached after 8 hours of noise exposure. Above 130 dB, any exposure to noise, even short-term, is considered highly harmful.
NEXELEC noise sensors measure the sound environment in interior spaces, helping to ensure the well-being of occupants.
In any indoor environment, lighting plays a crucial role in the productivity, concentration and well-being of occupants. Good lighting can boost energy, improve mood and reduce eyestrain.
Measuring brightness is therefore essential to guarantee the visual comfort, safety, energy efficiency and functionality of interior spaces.
