Relative humidity and temperature sensor COMFORT

wall-mountNB-IoTIoT

Overview
This sensor, configurable on NB‑IoT or LTE‑Cat‑M1 networks, monitors ambient temperature and relative humidity inside rooms to support occupant comfort management and energy optimisation.

IoT sensor highlights

• Designed and manufactured in France
• Worldwide cellular compatibility (NB‑IoT, LTE‑Cat‑M1)
• Easy on‑site configuration via the Adeunis NFC Configuration app
• Multi‑platform integration using LwM2M and MQTTS standards
• Up to 15 years battery autonomy in standard configuration
• Also available in LoRa / Sigfox variants

Primary functions

• Measurement: ambient temperature and humidity
• Alerting: configurable threshold alarms and network coverage alerts
• Transmission modes: periodic, event‑driven and logging modes (with configurable logging and blackout options)

Operation & fleet management
The device provides automatic network quality diagnosis, UTC time‑stamped data with remote synchronization, error and fault reporting (including configuration errors and low battery), and supports remote device management (individual or batch commands, configuration read/write, FOTA) via LwM2M.

Complementary information
On‑site parameterisation is available via NFC and automated provisioning on IoT platforms through LwM2M bootstrap. Secure communications are supported using DTLS with PSK and remote update capability for both application and modem firmware.
