The Nexelec FEEL is a 2-in-1 LoRaWAN room sensor that measures 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. FEEL combines high-accuracy sensing with a compact, minimalist enclosure suitable for free-standing placement or wall mounting. Configuration is done wirelessly via NFC using the Nexelec TOUCH smartphone app - no tools, no wiring, no need to open the enclosure. Key Features 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 Dual wireless connectivity: LoRaWAN and Sigfox (X580LS); LoRaWAN only (X580LR) 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 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 one SAFT LS14500 2600 mAh lithium battery. A second battery slot doubles available autonomy. 270° air circulation: Numerous side openings for better ambient air sampling Insect barrier: Integrated pest screen protects the sensing chamber 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 Calibration: Sensor calibration certificate from a COFRAC-accredited independent metrology laboratory Certifications: CE, UKCA, FCC Applications Office and commercial building climate monitoring Residential comfort monitoring Cold chain and storage environment 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. LoRaWAN gateway and network server not included. A LoRaWAN or Sigfox network must be available at the installation site. Battery life estimate is typical, 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 X580LR variant supports LoRaWAN only; the X580LS variant supports both LoRaWAN and Sigfox.
