USER GUIDE

Description

FM232g is an IoT LoRa sensor for monitoring gas consumption with a 10-minutes or 15-minutes time step (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 (also including batteries).

The sensor only transmits messages to an F-Link micro-bridge (to be purchased separately). Up to 10 sensors can be registered on a single F-Link. The F-Link micro-bridge receives these radio messages and forwards to Fludia data collect server, by means of the existing Internet connection. The F-Link can connect to the existing Internet box (DHCP protocol) through one of these two means: Wifi (F-Link can be provided with the Wifi password with the help of a smartphone or a PC) or provided Ethernet cable.

Data can be retrieved from the data collect server either through the API or by connecting to the dashboard and manually downloading a file for a selected period of time. An FTP solution can also be provided.
