2 General Description / ADT1 Communication
The LoRaWAN® module, which can be configured on a country-specific basis, establishes a connection with a
LoRaWAN®
Gateway and makes it possible to send the measurements to a LoRa network server . The LoRaWAN provid-
er can be selected freely. The easiest and most convenient way to access the collected data at the end of the
transmission chain is via
KOLIBRI Cloud from KELLER.
2.1 Pre-Configuration
The ADT1 are preconfigured on the open- source, decentralized network called “ The Things Network “. TTN is a contribu-
tor member of the LoRa Alliance and provide a set of open tools and a global, open network to connect things. This
means the ADT1 is ready to use without any configuration changes.
Nevertheless the ADT1 can be easily reconfigured through the USB interface to other network servers like Actility ,
Loriot etc.
2.2 Data Transmission / Technologie
LoRaWAN
®
: Lo ng Ra nge W ide A rea N etwork, is a protocol developed by the LoRa Alliance.
The peculiarity of this new protocol is the efficiency; because LoRaWAN
®
has the minimal power consumption, long
range of communication (up to 15km in rural areas) and secure data transmission (with AES -128 encryption).
The range of communication is around 2km in dense urban area, up to 15km in the rural areas and is influenced by
the position of the ADT1 and of the gateway, if the gateway is mounted in an high place the cover will be major than
if is mounted in a low place.
LoRaWAN
®
is part of a bigger category of technologies named LPWAN, that stands for Low Power Wide Area Net-
work, this technology was born for the necessity of sending and receiving messages from sensor that operate on
battery, using the smallest amount of energy available to preserve the battery energy.
2.3 KOLIBRI Cloud
The KOLIBRI Cloud from KELLER offers simple and convenient access to your measurement data with your own personal
login and SSL encryption. You can enjoy readily available data without the need to set up and maintain a database. The
measurements can be displayed as graphs in no time at all and the export function allows you to download your data as
Excel or CSV files. Measuring points are effortlessly and efficiently monitored with the integrated alarm system. For
instance, a warning can be triggered via e-mail if there is an increase in water level or a battery is running low. The
KOLIBRI Cloud API allows customer-specific software to call up measurements in a standardised JSON format via HTTPS.
