Nexelec RISE 3-in-1 Room Sensor

The Nexelec RISE is a 3-in-1 LoRaWAN room sensor that measures CO2, temperature, and humidity in offices, homes, and other indoor environments. All measurements transmit wirelessly to a secure cloud platform for remote monitoring and data logging.

RISE combines an NDIR CO2 sensor with temperature and humidity sensing in a single compact enclosure suited for free-standing placement or wall mounting. A color-coded indicator light and audible signal alert occupants when ventilation is needed. Configuration is done wirelessly via NFC using the Nexelec TOUCH smartphone app — no tools, no wiring, no need to open the enclosure.

Key Features

• CO2 measurement: NDIR sensor, resolution 1 ppm, accuracy ±(50 ppm + 3% of value), range 0–5,000 ppm. Analyzes air every 5 minutes; automatic weekly recalibration; manual calibration also possible.
• Temperature measurement: Resolution 0.1°C, accuracy ±0.2°C, range −30°C to +70°C
• Humidity measurement: Resolution 0.5% RH, accuracy ±2% RH, range 0–100% RH
• CO2 indicator light: Green/Orange/Red LED visible from over 10 m changes with CO2 level to alert occupants when ventilation is needed. ppm trigger threshold is reconfigurable via NFC or remotely via LoRaWAN.
• Audible signal tone: Notifies occupants when indoor air quality deteriorates. Can be activated or deactivated locally or remotely.
• Local data storage: Built-in micro SD card stores up to 10 years of measurements — data is preserved in the event of a network outage or power cut.
• Dual wireless connectivity: LoRaWAN and Sigfox (X520LS); LoRaWAN only (X520LR)
• Multi-band LoRaWAN: Configurable for EU868, US915, AS923, and other regional frequencies via NFC
• NFC configuration: Over 25 parameters adjustable via Nexelec TOUCH app — measurement interval, transmission interval, LED/buzzer indicators, radio frequency band, and more. Settings can be made through the packaging before the battery is installed.
• Data transmission modes: Periodic, on-change, and bundled datalog with redundancy (each frame sent three times to maximize gateway reception)
• End-to-end encryption: Double AES-128 encryption on all transmitted data
• Long battery life: Up to 20 years(1) with two SAFT LS14500 2600 mAh lithium batteries (both included)
• On-demand measurement: Front button triggers an immediate measurement and data transmission
• Anti-tamper: Lockable mounting base; alert message sent if the sensor is removed
• Mounting: Free-standing, wall-mounted (screws/plugs included), or 3M adhesive fastener (included) — no drilling required
• 270° air circulation: Numerous side openings for better ambient air sampling
• Insect barrier: Integrated pest screen protects the sensing chamber
• Calibration: Calibration certificate for CO2, temperature, and humidity measurements from a COFRAC-accredited independent metrology laboratory
• Regulatory compliance: Direct-reading NDIR CO2 sensor compliant with French and international standards for measuring CO2 concentration in indoor air
• Certifications: CE, UKCA, FCC

Applications

• Indoor air quality monitoring in offices, classrooms, and public buildings
• Ventilation control and HVAC automation based on CO2 levels
• Regulatory compliance monitoring for indoor air quality standards
• Residential comfort and health monitoring
• Facility management and building automation
• Large-scale IoT sensor deployments via LoRaWAN or Sigfox networks
• Integration with NAVIXIS IoT platform for dashboard visualization, threshold alerts, and data export

Important Notes

• Intended for indoor use only. Operating range: −20°C to +50°C, 0–99% RH non-condensing.
• NDIR CO2 sensor requires a minimum ambient CO2 level of about 400 ppm for several consecutive hours to maintain automatic recalibration accuracy. Suitable for offices, classrooms, and shared spaces; not recommended for spaces that are never unoccupied or never ventilated.
• LoRaWAN gateway and network server not included. A LoRaWAN or Sigfox network must be available at the installation site.
• Battery life estimate is not guaranteed; actual life depends on configuration, environment, and network conditions. Use the Nexelec VOLT tool to calculate projected autonomy for your deployment.
• NFC configuration requires the free Nexelec TOUCH app (Android or iOS).
• The X520LR variant supports LoRaWAN only; the X520LS variant supports both LoRaWAN and Sigfox.
