Indoor air quality sensor WAVE+

CO2relative humiditytemperature

Overview
The WAVE+ (reference X230LR) is a 5-in-1 connected room sensor for professional indoor monitoring. It provides direct readings of temperature, humidity, CO2, presence and ambient brightness on an E-ink display. The device supports multi-band LoRaWAN, local NFC configuration and secure cloud access for remote reading and management.

Key features

• E-ink display: low power consumption and high readability; configurable locally via NFC or remotely.
• 5-in-1 measurements: temperature, humidity, CO2, PIR presence and brightness for multi-purpose building management.
• CO2 visual alerts: tricolour LED (Green/Orange/Red) visible from over 10 m; thresholds reconfigurable via NFC or LoRaWAN.
• Multi-band LoRaWAN transceiver with redundancy and historical-data mode to limit losses.
• NFC configuration with the Nexelec TOUCH app: fast, secure parameter changes (25+ configurable parameters).
• Installation options: 3M adhesive, lockable mounting base, anti-tear detection and front push-button for instant measurement.
• End-to-end security: double AES128 encryption for data protection.

Sensors and measurements

• Temperature: direct-reading sensor, resolution 0.1°C, accuracy ±0.2°C.
• Humidity: resolution 0.5% RH, accuracy ±2% RH; long-term stability.
• CO2: resolution 1 ppm, accuracy ±(50 ppm + 3% of value); sampling every 5 minutes; automatic weekly recalibration (manual possible); COFRAC-accredited calibration certificate available.
• Brightness: resolution 5 lux, accuracy ±5 lux, range 0–5,000 lux for lighting optimisation.
• Presence (PIR): passive infrared detection, 92° angle, detection distance up to 6 m for occupancy and control scenarios.

CO2 monitoring details
CO2 is measured every 5 minutes. The device issues a configurable visual alert via the LED (Green/Orange/Red) to prompt ventilation. Thresholds and alert behaviour can be reconfigured locally by NFC or remotely via LoRaWAN. Calibration certificate is provided by a COFRAC‑accredited laboratory; automatic weekly recalibration with option for manual calibration.

Connectivity and data handling

• Multi-band LoRaWAN: configurable region frequencies (EU868, US915, AU923, etc.) with optimized PCB antenna.
• Transmission modes: periodic, on-change, grouped datalog frames with redundancy (multiple sends) to maximize reception.
• Historical Data mode + redundancy to reduce radio traffic while preserving measurements.
• API, webhook notifications and data export via the NAVIXIS IoT platform (export formats: .pdf, .csv).
• Enhanced security: double AES128 encryption for end-to-end data protection.

Installation, mounting and security

• Mounting: wall-mounted or free-standing.
• 3M adhesive fastener for quick, drill-free installation; lockable mounting base to reduce theft risk.
• Anti-tear detection: triggers an alert if the product is removed from its base.
• Front push-button for immediate measurement and fast data sharing.

Power & autonomy

• Power supply: 3 replaceable lithium battery slots; batteries included in the set.
• High-performance battery options and additional holders can extend autonomy (manufacturer examples: typical scenarios up to many years depending on configuration).
