The connected room sensor designed for professionals
The data collected by room sensors is essential to the smooth operation of many buildings.
Our products offer exceptional reliability, stable IoT connectivity, long battery life and consistently accurate measurements.
Easy to manage and configure, they can be deployed in large numbers to ensure efficient operations and satisfied customers.
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
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).
Regulatory compliance
Take control of your environment by ensuring healthy indoor air. Direct-reading sensor compliant with French and international standards for measuring CO2 concentration
Indicator light visible from over 10 metres
The powerful Green / Orange / Red indicator changes with the CO2 level. ppm" trigger threshold can be reconfigured locally via wireless NFC or remotely via LoRaWAN
Comprehensive environmental monitoring
With its 3 dedicated sensors, SIGN offers lighting and energy optimization, acoustic monitoring, space and safety management, and automation scenario options
Sound under control
Measures noise and identifies noise pollution. Helps preserve a calm and peaceful environment
Presence detection
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 measurements
To avoid any risk of erroneous measurements, particular attention has been paid to integrating the temperature and humidity sensors into the product.
Rigorous testing and strict validation protocols guarantee operation in extreme operating conditions ranging from -20°C to +50°C and from 0 to 99% ambient humidity
Long-term measurement reliability
Guaranteed consistency and accuracy, with no measurement drift over time
Regulatory compliance
Sensor calibration certificate issued by a COFRAC-accredited independant metrology laboratory

Superior performance for optimal LoRaWAN® data transmission
Multi-band LoRaWAN transceiver
With the Nexelec TOUCH application and NFC technology, you can quickly and easily configure the product to transmit on the frequency of your choice: Europe (868MHz), USA (915MHz), Australia (923MHz), etc.
No more data loss!
Historical Data mode + Redundancy function: measurements can be grouped in a single LoRaWAN frame to limit the number of radio transmissions and are sent 3 times to maximize their reception by the network gateway.
Optimized PCB radio antenna
Designed to ensure reliable radio connectivity, even in harsh environments, while limiting power consumption to extend battery life
Enhanced cyber security
Data transmitted by the product is secured from end to end using double AES128 encryption.
QR'LOOK simplifies the use of room sensors

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.
