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. RISE+ adds an E-Ink screen to the RISE platform, giving occupants a direct on-device reading of current conditions. All measurements also transmit wirelessly to a secure cloud platform for remote monitoring and data logging.

RISE+ combines an NDIR CO2 sensor with temperature and humidity sensing and a built-in E-Ink display in a 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

• E-Ink screen: Displays current CO2, temperature, and humidity directly on the sensor. Low power consumption, high readability even in direct sunlight, no reflections or excessive brightness. Screen layout is fully configurable locally via NFC or remotely via LoRaWAN.
• 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.
• LoRaWAN connectivity: LoRaWAN only (X220LR)
• Multi-band LoRaWAN: Configurable for EU868, US915, AU923, 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 15 years(1) with three SAFT LS14500 2600 mAh lithium batteries (all three 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 with on-site display for occupants
• Ventilation control and HVAC automation based on CO2 levels
• Regulatory compliance monitoring for indoor air quality standards
• Spaces where occupants need to read current CO2 levels without a separate display or app
• Residential comfort and health monitoring
• Facility management and building automation
• Large-scale IoT sensor deployments via LoRaWAN networks
• Integration with NAVIXIS IoT platform for dashboard visualization, threshold alerts, and data export

Important Notes

• Intended for indoor use only. Operating range: 0°C to +50°C, 0–99% RH non-condensing. Note: the operating temperature lower limit is 0°C, not −20°C — the E-Ink display's operating range is narrower than the sensors alone.
• 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.
• RISE+ supports LoRaWAN only. There is no Sigfox variant.
• LoRaWAN gateway and network server not included. A LoRaWAN 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).
