Relative humidity and temperature sensor COMFORT SERENITY

wall-mountNB-IoTLoRa

Overview
This sensor, configurable on NB‑IoT or LTE Cat‑M1 cellular networks, measures temperature, humidity, volatile organic compounds (VOCs) and CO2 to optimise indoor comfort and energy consumption. It transmits validated, time‑stamped data to support ambient comfort control and energy savings.

Highlights of the cellular IoT sensor

• Designed and manufactured in France
• Worldwide cellular compatibility (NB‑IoT, LTE‑M)
• Easy deployment using Adeunis NFC configuration apps
• Multi‑platform integration via LwM2M and MQTTS/MQTT standards
• Up to 10 years battery life with standard configuration
• Also available in LoRa / Sigfox versions

Deploy simply and quickly

• Selectable connectivity: NB‑IoT or LTE‑M networks
• Strong in‑building penetration for reliable indoor coverage
• On‑site parameterisation using NFC
• Protocol compatibility: LwM2M and MQTT
• Automated provisioning via LwM2M bootstrapping

Measure and alert as needed

• Monitor temperature, humidity, CO2 concentration, occupancy and relative VOC variations
• Trigger alarms based on configurable thresholds
• Flexible transmission modes: periodic, event‑driven and with historical logging

Alert / Inform / Indicate

• Alarm triggers for threshold exceedance or network faults
• Real‑time CO2 indication via a configurable light indicator (indicator can be disabled)

Operate and manage fleet

• Long‑term fleet operation with LwM2M: standardized remote device management (commands, configuration read/write, FOTA)
• Remote configuration via an LwM2M server and local NFC for network, server and application parameter setup

Documents & Tools

• User guides and technical documentation (datasheet, installation guide, release notes and LwM2M/MQTT user guides) available to support configuration, integration and operation
