Relative humidity and temperature sensor FEEL+

wall-mountflush-mountresistance

Overview
The FEEL+ is a 2-in-1 room sensor for temperature and humidity measurement. Key product elements include an E-Ink screen for direct reading, LoRaWAN connectivity for remote reading and secure cloud storage, NFC configuration and options for wall-mounted or freestanding installation.

Display & user interface

• E-Ink screen: low power consumption, high readability even in direct sunlight; fully configurable; display can be reconfigured remotely or via NFC.
• Front button: measure room parameters with one click and share data immediately.

Connectivity & security

• LoRaWAN connectivity — multi-band LoRaWAN transceiver (configurable frequencies: EU868, US915, AU923, etc.).
• Optimized PCB radio antenna for reliable reception in harsh environments.
• Data transmission: periodic, grouped data (datalog) with transmission redundancy (measurements can be grouped and sent multiple times to maximize reception).
• Enhanced cyber security: end-to-end protection using double AES128 encryption.
• Historical Data mode + Redundancy function to limit number of radio transmissions and maximize reception.

Sensors & measurement

• Measures ambient temperature and relative humidity for improved indoor comfort (offices, homes, buildings).
• Temperature accuracy: ±0.2°C; measurement range: -30°C to +70°C.
• Humidity accuracy: ±2% RH; measuring range: 0 – 100% RH.
• Designed and validated for reliable operation in extreme conditions: operating conditions noted include -20°C to +50°C in validation notes; recommended terms of use: Temperature 0°C to +50°C, Humidity 0% RH to 99% RH (non-condensing).

Configuration & management

• NFC configuration via the Nexelec TOUCH application to set over 25 parameters (measurement/transmission frequency, indicators, chosen LoRaWAN frequency, etc.).
• Settings can be performed without powering the sensor by using NFC through packaging.
• QR'LOOK label option: QR code label near sensors to inform occupants and provide online guidance, instructions and resources.

Installation & mounting

• Fast installation: free-standing, wall-mounted or compatible with single-user flush-mounting boxes (SIGN variant).
• 3M adhesive fastener included for quick non-drilling installation.
• Lockable mounting base for anti-theft protection and anti-tear detection that triggers an alert if removed from its base.

Power & autonomy

• 3 battery slots (replaceable batteries).
• Includes 1 SAFT high-energy battery (examples on site mention SAFT 2600 mAh or LS14500 for autonomy calculations).
• Typical autonomy example: more than 6 years in typical configuration; option to extend to up to 20 years with additional battery holders depending on configuration and usage profile.

Content & warranty

• Content of box: 1 sensor, 3 batteries included, 1 mounting base, 2 nylon screws and plugs, 1 3M® adhesive fastener.
• Warranty: 2 years.

Compliance & certification

• Sensor calibration certificate available from a COFRAC-accredited independent metrology laboratory.
• Certifications listed include CE, UKCA and FCC.
