CO2 sensor / Lorawan sensor / sonde CO2 connectée

Monitors Indoor Air Quality and controls VOC emissions

SIGN 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.

SIGN allows you to manage ventilation in enclosed spaces and protect occupants’ health by limiting exposure to pollutants.

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.

Monitor CO2 at a glance!

SIGN analyzes CO2 levels every 5 minutes and visually alerts occupants when it’s time to ventilate to renew indoor air

CO2 sensor / Lorawan sensor / sonde CO2 connectée

Measurement accuracy

Calibration certificate issued by a COFRAC-accredited metrology laboratory. The CO2 sensor analyzes the air every 5 minutes and automatically recalibrates every week (manual calibration possible).

Frequently Asked Questions

Our experts answer your questions

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.

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

NDIR (Non-Dispersive Infrared) sensors offer highly accurate measurement of CO2 levels. They use infrared spectroscopy to specifically detect CO2 molecules, enabling reliable and consistent measurements.

NDIR sensors are designed to maintain their calibration and accuracy over long periods, making them a durable choice for continuous monitoring of CO2 levels.

NDIR sensors are effective and reliable in an environment where CO2 levels reach at least a minimum of 400 ppm for several consecutive hours: at night and at weekends in communal areas, during the day in a bedroom.
