The advantages of SENSE

Your ally for Indoor Air Quality

Thanks to its 3 sensors of CO2, VOC and fine particles, SENSE is your best asset against the atmospheric pollution which is harmful for the health of the occupants.  


10 years of use

With its charger and cable USB-C cable and its high-performance components, SENSE has a 10-year autonomy.

Equipped with atmospheric sensors

With its presence, brightness and sound sensors, SENSE allows to analyse the activity rate of the areas and to measure the sound level. These multi-parameter measurements allow to define the strategies of heating and air renewal in your closed spaces.


Monitor Fine Particle Level

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


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


SENSE 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 SENSE fine particle sensor is factory calibrated and requires no maintenance.


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.

SENSE 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.

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.

Connect your sensors


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


IoT network connectivity is suitable for all use cases requiring enhanced Indoor Air Quality (IAQ) monitoring. No internet connection is required.

Detector from 269€ excluding tax

Install your sensors easily

SENSE 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.

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

Monitor and 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.

Designed for communities and businesses

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

SENSE is sober and elegant and fits in every type of interior.

Reliability of CO2 measurements


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


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

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


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

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

Manual calibration of the CO2 sensor is also possible.

Ventilate only when necessary


SENSE 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*.
