3.5. Howdoesthesensornodecommunicatewiththegateway?
The sensor node and gateway communicates with each other using the LoRa protocol. LoRa is
a long-ranged, low-frequency, wireless communications protocol, designed for transmitting small
data packages with minimum power consumption.
The sensor node transmits data packages to the gateway over LoRa regularly at a set interval.
Theintervalatwhichthesensornodetransmitsdatapackagesisconguredinthesensornode’s
rmware.Defaultintervalis60seconds.TheLEDonthesensornodeblinkswithabluelightas
data is transmitted.
The sensor node must be placed in clear view of the gateway, to make sure that there is no inter-
ference in the communication. The sensor node is able to transmit data over a maximum distance
of 150 metres.
The gateway is provided with two antennas, which facilitates communication between the sensor
node and gateway, and between the gateway and the cloud database. The antennas must be
installedasshowninthegureontheright.
The sensor node automatically established a connection with the gateway once it is powered on.

3.6. Howdoesthegatewaycommunicatewiththeclouddatabase?
The gateway communicates with the cloud database either over a 4G cellular connection, or over
ethernet. The LED above the globe symbol () on the gateway is lit with a steady blue light when the
gateway is connected.
ThegatewayisprovidedwithaSIMcardwhichfacilitiescellularcommunication.TheSIMcard
isspeciallyconguredbyRapidbeforedelivery.Whenthegatewayispoweredon,thegateway
immediately established communication with the cloud database.
It is also possible to connect an ethernet cable to the gateway’s ethernet port, if a more stable con-
nectionisrequired.Thegatewayisplug-and-play,andyourrewalldoesnotrequireconguration
in order for the gateway to communicate over ethernet.
3.7. Ismydatalostifthesensornodeand/orgatewaylosesconnection?
Yes, neither the sensor node nor the gateway is provided with secondary memory, meaning that
data is not stored before it is transmitted to the database. You will however not lose data that is
already stored in the database, if the connection is lost.
