1. PRODUCT OVERVIEW
1.1. General description
The Adeunis COMFORT is a ready-to-use IoT sensor that meets the needs of users for indoor
monitoring of temperature and ambient humidity. This product is also equipped with an NFC
interface, which allows for quick and easy configuration with a smartphone.
Thermal comfort data are transmitted via a cellular IoT network (NB-IoT or LTE-Cat-M1) to a server.
No additional equipment (gateway, router, etc.) is required for data transmission.
The COMFORT integrates the LwM2M (Lightweight Machine to Machine) standard, which enables
users to achieve integration and maintenance savings, reduce deployment costs, strengthen sensor
fleet security, and optimize product battery life.
The product operates autonomously and intermittently. It measures temperature and humidity data
from the onboard sensors in "sleep" mode (PSM) and stores the data in its local memory. It then
wakes up at preconfigured intervals to transmit the stored data using the LwM2M protocol.
The product is powered by a replaceable battery pack and has been designed to work for over 15
years without maintenance (device configuration : 1 sampling every 60 mins, 1 transmission every 60
mins, LEDs enabled).
