Professional ambient sensor

Technical specifications

The LoRaWAN-connected room sensor designed for professionals: SIGN provides optimum management of ventilation in enclosed spaces. Its precise sensors (temperature, humidity, pollutants) help protect occupants’ health by limiting exposure to pollutants.

Complete environmental monitoring

• Total Volatile Organic Compounds (TVOC) sensor: Based on highly sensitive MOx-type detection technology.
• Presence detection: motion sensor detects people up to 6 meters away
• Noise control: Measures noise and identifies noise pollution
• Ambient light measurement: Brightness sensor measures the amount of light in the room
• Stores measured data: Integrated micro SD card. Up to 10 years of sensor measurements stored in memory

Monitor Carbon Dioxide (CO2) at a glance

Powerful Green / Orange / Red indicator changes with CO2 level (ppm). The “ppm” trigger threshold of the sleek, white product can be reconfigured locally via wireless NFC, or remotely via LoRaWAN.

Reliable, precise temperature and humidity measurement

To avoid any risk of erroneous measurements or data, particular attention has been paid to integrating the temperature and humidity sensors into the product. The result is more accurate data output.

Quick installation and mounting

3M adhesive mounting, anti-theft protection, anti-pull-out detection

Autonomy of over 3 years*

Includes 2 SAFT 2600 mAh high-density replaceable batteries and 1 USB-C plug for continuous power supply

NFC configuration

The Nexelec TOUCH app, combined with NFC technology, enables wireless adjustment of the white product simply by bringing a smartphone close to your sensor, making the process much simpler for users.

Frequently asked questions

Why measure CO2?

Correct ventilation of communal areas helps reduce the risk of airborne viruses spreading.
By measuring CO2 levels, you can quickly check the quality of air renewal, and encourage occupants to air the room if necessary.

NEXELEC’s CO2 sensors provide reliable, precise measurement of CO2 concentration.

Why measure ambient parameters in work environments?

Depending on models and accessories, Nexelec products offer lighting and energy optimization, acoustic monitoring, space and safety management, and automation scenario options.

Why use an NDIR CO2 sensor?

NDIR (Non-Dispersive Infrared) sensors offer the highest available accuracy in measuring CO2 levels. NDIR sensors are designed to maintain their calibration and accuracy over long periods, making them a durable choice for continuous monitoring of CO2 levels, and ambient air quality.
