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.

Interpretation of CO2

 

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.

VOC interpretation

 

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.

Interpretation of PM

 

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.

Interpretation of HCHO

 

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.

Interpretation of CO

Depending on the model, products offer lighting and energy optimization, acoustic monitoring, space and safety management, and automation scenario options.

NEXELEC sensors can measure CO2, depending on the model. 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 the ppm level is too high, ventilate the premises as soon as possible.

Interpretation of CO2

Correct ventilation of communal areas helps reduce the risk of viruses spreading through the air.
Measuring CO2 levels enables you to quickly check the quality of air renewal, and encourages occupants to air the room if necessary.

CO2 can cause headaches, drowsiness, difficulty concentrating, mild nausea and rapid heart rate.
NEXELEC’s CO2 sensors provide reliable and accurate measurement of CO2 concentration.

Atmosphere

In an enclosed space, heat rises and stagnates at the ceiling, where the temperature is de facto a little higher than in the rest of the room. To ensure correct measurement of ambient temperature, we recommend mounting the detector on a wall 50 cm below the ceiling.

Measuring temperature in indoor environments is important for several reasons:

  • Thermal comfort: Temperature plays a crucial role in the comfort of the occupants of an indoor space. An environment that is too hot or too cold can affect people’s well-being and productivity
  • Health: Extreme temperatures can have adverse effects on health. Temperatures that are too high can lead to dehydration and exhaustion, while temperatures that are too low can cause hypothermia. Temperature monitoring is therefore important to ensure healthy living conditions
  • Energy efficiency: Maintaining the right temperature optimizes the energy efficiency of heating, ventilation and air-conditioning (HVAC) systems. Accurate temperature monitoring allows these systems to be regulated appropriately, avoiding excessive energy consumption

NEXELEC sensors can measure various environmental parameters such as noise or ambient brightness. Depending on country and environment, and according to WHO recommendations, thresholds may vary.

 

Noise level

Exposure to excessive noise can lead to hearing fatigue and long-term deafness. If the measured noise level is too high, identify the source and move away from it, or use hearing protection.

Brightness

Ambient lighting has a significant impact on our ability to work and maintain your productivity. If insufficient, it can lead to ophthalmic fatigue.

brightness interpretation

To reduce noise pollution, it is useful to implement corrective measures:

  • Use quiet machines
  • Soundproof premises or buildings
  • Equip occupants with earplugs
  • Create isolated areas for noisy calls or machines.

NEXELEC noise and sound level sensors help reduce noise pollution in indoor spaces.

Noise is a constant feature of everyday life. But unfortunately, it can be harmful to humans. In France, 3 million employees are exposed to excessive noise levels in the workplace. Without realizing it, hearing loss can set in very quickly and lead to deafness.

To anticipate these risks, NEXELEC noise sensors help you keep an eye on the noise level around you on a daily basis, in a preventive manner.

 

Poor noise management will also have an impact on occupants’ concentration levels, influencing their alertness too. The impact is not only physical, but can also be psychological. Studies show that exposure to noise increases levels of the stress hormone cortisol. This can lead to increased anxiety, fatigue, depression and even sleep disturbance.

NEXELEC noise sensors enable you to effectively monitor the sound environment in indoor 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.

Measuring occupancy rates is essential for the smooth running of interior spaces. Measurements can be analyzed to make informed decisions: optimize space layout, identify under-used or overcrowded areas, and adjust resources according to actual needs.

With NEXELEC presence sensors, you can maximize space efficiency, reduce costs and enhance the occupant experience.

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.

Presence sensors contribute to energy savings by detecting the presence or absence of people in a space. This means that lighting, heating, ventilation and other systems can be automatically adjusted according to this detection.

By reducing unnecessary energy consumption, NEXELEC presence sensors contribute to significant energy savings and lower energy costs.
