Indoor air quality sensor SENSE

roomCO2VOC

Short product summary
SENSE is a 9-in-1 connected room sensor designed for continuous monitoring of indoor air quality and environmental parameters. On-board iZiAiR data analysis ranks pollutants and supports decision-making for ventilation, filtration and other corrective actions. The device supports remote reading, secure cloud storage and local NFC configuration.

Measured parameters

• Particulate Matter (PM1, PM2.5, PM10)
• Carbon Dioxide (CO2)
• Total Volatile Organic Compounds (TVOC)
• Temperature
• Humidity
• Atmospheric pressure
• Brightness (lux)
• Noise (dB)
• Presence (PIR motion)

Key features

• Air 360° detection design for fast, representative ambient air sampling.
• Embedded iZiAiR algorithm to analyse up to 9 pollutants and prioritise hazardousness.
• Front instantaneous measurement button (optionally disabled) for quick readings and sharing.
• Visual CO2 indicator (Green / Orange / Red) to signal ventilation needs.
• TVOC sensor based on MOx technology suitable for humid and dusty environments.
• Optical particulate sensor (laser scattering) measuring PM1 / PM2.5 / PM10 with long service life components.
• NFC configuration via Nexelec TOUCH app (over 25 configurable parameters).
• LoRaWAN connectivity with optimized PCB antenna and transmission modes (Historical Data or Periodic Send) to limit data loss.
• End-to-end cybersecurity with double AES128 encryption.
• Flexible installation: free‑standing or wall‑mounted; adhesive mount included; lockable mounting base for anti‑theft.
• Low power consumption; powered via a single USB‑C port (AC adapter and 1.8 m USB‑C cable included).

Use cases and benefits
SENSE enables monitoring and management of indoor air quality to support ventilation strategies, filtration and purification decisions; optimise energy and lighting; monitor acoustics; and enable space management and security automation. The device provides direct-reading compliance for CO2 measurements and can be supplied with a calibration certificate validating CO2, temperature and humidity accuracy.
