NDIR CO2 sensor AERO

USBLoRaWANwireless

Product overview
The AERO CO2 is a connected 3-in-1 room sensor designed for indoor air quality monitoring: it measures carbon dioxide (CO2), temperature and humidity and provides remote reading via a secure cloud space. The device supports free-standing or wall-mounted installation and includes an adhesive mount and a lockable mounting base for anti-theft protection.

Key features

• 3-in-1 measurements: CO2, temperature, humidity
• Connected: LoRaWAN transmission (EU868) with secure cloud access and remote reading
• Visual LED indicator: three-color LED (Green / Orange / Red) for immediate CO2 level indication
• NFC configuration via Nexelec TOUCH app for local reconfiguration of ppm thresholds
• Instantaneous measurement button on the front (can be disabled)
• Air 360° detection design for rapid ambient air analysis
• Optimised PCB radio antenna and transmission modes: Historical Data mode and Periodic Send mode to maximise gateway reception
• Enhanced cybersecurity: end-to-end double AES128 encryption
• Easy installation: free-standing or wall-mounted; adhesive mount and lockable base included

How it notifies and operates
The sensor samples ambient air every 10 minutes and uses the LED indicator to alert occupants when ventilation is recommended. CO2 thresholds (ppm) can be reconfigured locally via NFC using the Nexelec TOUCH app. Transmission modes (Historical Data or Periodic Send) are available to ensure robust data delivery to LoRaWAN gateways.

Calibration and compliance
Measurement accuracy for CO2, temperature and humidity is validated by an accredited metrology laboratory (COFRAC for combined measurements). The device performs automatic CO2 calibration every 8 days; manual calibration is possible using the front button sequence described in the product documentation. The sensor is a direct-reading device compliant with French standards for indoor CO2 measurement.
