Analyse in depth the Air Quality of workspaces

Les avantages de ATMO

10-in-1 sensor

With its light, presence and sound sensors, ATMO is able to measure comfort of occupants : sound level, brightness, motion detection in your closed spaces. ATMO will allow you to define your heating and air renewal strategies.

Symbol of Nexelec's know-how

ATMO is the most complete detector of our range. This 10-in-1 sensors provides information on the air quality and the working environment of your teams. ATMO can discriminate specific Volatile Organic Compounds (VOC) such as formaldehyde (HCHO).

Spot high concentrations of Formaldehyde

Formaldehyde is frequently present in the indoor air of buildings due to air pollution linked to certain coatings, floors, or furniture.


ATMO will continuously analyse formaldehyde emissions to help you identify the most exposed spaces.


Control exposure to VOCs


Volatile Organic Compounds (or VOCs) are characterized by their high volatility and spread easily in the atmosphere.

VOCs can induce nausea and contribute to olfactive pollution.

ATMO will continuously measure VOCs and characterise their evolution over time in order to help ventilate the premises at the right time.

Your workspace under control



With its multi-parameter measurement sensors, SENSE is specifically designed to analyse the working environment and thus quickly identify possible improvements.

Thanks to its microphone, capable of determining the average noise level and the noise peaks, SENSE keeps track of working conditions.

 The light and motion sensors allow to determine the real activity rate of the spaces to adapt the heating and ventilation strategies of the buildings accordingly.

Monitor Fine Particle levels

The finest airborne dusts and particles penetrate deep into the lungs where they can cause inflammation and impair overall lung functions.


ATMO is equipped with a fine particle sensor capable of measuring and differentiating PM1, PM2.5 and PM10 concentrations.


ATMO will allow to analyse the exposure of a living area to this air pollution and help to take the most appropriate remedies for the situation : ventilation, air filtration, air purifier...


The ATMO fine particle sensor is factory calibrated and requires no maintenance.

Connect your sensors

Atmo is a connected multi-parameter measurement device equipped with a wireless radio communication module LoRaWAN.

No internet connection is required.


IoT network connectivity is suitable for all use cases requiring enhanced Indoor Air Quality (IAQ) monitoring. 

Detector from 269€ excluding tax

Install your sensors easily

ATMO can be installed on the wall thanks to its anti-theft fixing system or on a table, in order to be easily moved from one space to another.

ATMO runs on a USB-C power supply for a simple and easy integration in any working environment.


Analyse Indoor Air Quality 

In our app App.Nexelec  or that of our partners, easily view the history of your data in the form of graphs or reports. Continuously observe the environment of interior spaces, remotely and via 100% secure access. Analyze indoor air quality, view ambient data and configure the notifications that interest you.

In collective spaces, the display of the CO2 level on a screen is potentially stressful for users and can make it harder to interpret the measurements.

The Green / Orange / Red indicator simplifies immediate understanding and the implementation of actions adapted to the air renewal.


The detector's indicator light is fully configurable. 

Simply download the free App.Nexelec application from the Google Play Store on your Android smartphone and configure your detector in "contactless" NFC to change the thresholds that trigger the indicator light.


By default, the light turns Orange at 1000 ppm and Red at 1700 ppm

Reliability of CO2 measurements

The measurement of the CO2 level is a reliable indicator of the good air renewal in a closed space.


ATMO is equipped with a state-of-the-art NDIR CO2 sensor.

The accuracy of the CO2 sensor measurements has been validated by an independent COFRAC approved laboratory.


No maintenance required and no risk of drifting measurements over time. 

ATMO integrates an automatic and weekly recalibration function of its CO2 sensor.

Manual calibration of the CO2 sensor is also possible.

Designed for communities and businesses

ATMO is a robust product, totally sealed and non-removable, perfectly adapted to the requirements of all establishments receiving the public.


Sober and elegant, ATMO integrates with every type of interior.


The sensor does not have a screen for more discretion and a reinforced reliability.

Ventilate only when necessary


ATMO continuously analyses the Air Quality and visually alerts the occupants when it is time to ventilate to renew the indoor air.


Thanks to its LoRaWAN wireless IoT communication module, the ambient data can be accessed remotely, simply from a smartphone or a computer screen*.
