Description of the IoT temperature and humidity sensor
What are the technical characteristics of the connected sensor?
Features
- Periodic transmission of temperature and humidity data (with or without logging of measured values) and/or when thresholds are exceeded (high and/or low).
- Redundancy with configurable number of data repeats per frame
- 1 digital input to detect one or more changes of state and send an associated frame
- 1 button connected to detect one or more events (by pressing a button) and send an associated frame
- Configurable alarm repetition in the event of a persistent event
- Configurable life frame
- Configuration:
- local, via a USB-C port
- remote, via the network, enabling periodicity, transmission modes and alarm thresholds to be set.
- Product error, configuration error and low battery alerts

Indoor Air Quality: how and why should it be measured? What is required by the regulation? How to act?
Dalkia is helping the Valenciennes Hospital to set up ambient temperature monitoring in its buildings.
Indoor air quality (IAQ) is reportedly 5 to 10 times worse than outdoor air quality.
