3 - Sense LWEU Series
Installation
These devices themselves don’t require any specific installation. They are portable instruments. Upon
shipping, they are automatically registered to the NSnappy service and are ready for use.
Connections
Sense LWEU-N series models use a LoRaWAN wireless connection to send the data to the
cloud-based NSnappy service. For the LoRaWAN radio reception to work, an
NSnappy Hub 4G
LWEU-N
gateway device needs to be installed on all sites where these instruments will be used.
Please refer to the manual of the hub device for its installation instructions.
