FM432g - IoT LoRaWAN Sensor - Gas

**FM432g** is an IoT LoRaWAN sensor for monitoring gas consumption. It provides the ideal starting point for analyzing consumption levels and offers complete interoperability with LoRa IoT networks to quickly report any changes. It is the ideal device for implementing energy efficiency services dedicated to small and medium-sized buildings.

FM432g connects to LoRaWAN communication networks so that data can be collected at regular intervals (time step of 10, 15 minutes, or 1 hour (option to be selected)). The sensor consists of an optical reading head (to be installed on the existing main gas meter) and a radio box (which also includes batteries).

Data can be decoded autonomously (payload format described) or sent to the Fludia server to be decoded and retrieved via an API.

- **Plug & Play**: Non-intrusive optical reading technology, easy and quick to install, no electrical contact
- **Universal**: Compatible with all gas meters with mechanical display
- **Communication**: Guaranteed connectivity to all LoRaWAN 1.0 networks
- **Accuracy**: Consumption measurement in 10min, 15min or 1 hour
- **No ATEX Certification**
- Designed and manufactured in France
