Indoor air quality sensor ATMO+

CO2VOCrelative humidity

Product overview
ATMO+ is a 10-in-1 connected room sensor for continuous indoor air quality and environmental monitoring. It combines factory-calibrated sensors, an E-Ink display for low-power direct reading, on-board analysis and secure remote access via LoRaWAN and cloud integration. Designed for long-term stability and robust data retention, ATMO+ supports facility management, IAQ compliance and smart-building use cases.

Main features

• E-Ink display: low-power, high-contrast readout; configurable remotely or via NFC.
• Connected & intelligent: on-board analysis algorithm, remote reading, secure cloud access and double AES128 encryption.
• Comprehensive sensing: Formaldehyde (HCHO), VOCs, CO2, PM1/PM2.5/PM10, Temperature, Humidity, Atmospheric pressure, Brightness (lux), Noise (dB), Presence (PIR), and VAPE detection.
• Measurement reliability: factory-calibrated HCHO sensor; CO2 dual-channel NDIR with COFRAC-accredited calibration certificate; automatic weekly CO2 recalibration (manual option available).
• Indicators & alerts: visible Green/Orange/Red LED (visible >10 m), configurable thresholds via NFC or remotely (LoRaWAN); optional audible alarm.
• Data robustness: built-in microSD for up to 10 years of local storage; Historical Data mode and redundancy (grouping and repeated transmissions).
• Connectivity: multi-band LoRaWAN transceiver (EU868 / US915 / AU923…, configurable), optimized PCB antenna.
• Easy configuration: NFC setup with Nexelec TOUCH app (over 25 configurable parameters), allows parameterization without powering the sensor from its battery.
• Installation & security: 3M® adhesive fastener for quick mounting; lockable mounting base and anti-tear detection for theft protection; wall-mounted or free-standing options.
• Power & lifetime: USB-C power input; very low power consumption and service life in excess of 10 years.
