The customer expressed interest in
opportunities of building the ecosystem of data collecting, primary processing,
transmission, storage, and post-processing via Long Range technology at the
maximum possible distances. Long Range (LoRa) devices provide the
opportunity to solve problems with connection to the premises and devices. The
technology could extend to the periphery of municipal and industrial
operations, supply chains, agricultural fields, and even to your home and yard.
Thanks to the low-power wireless qualities of LoRa Technology allows the use of
low-cost sensors to transmit data from the object to the cloud, where they can
be analyzed to improve performance.
CHALLENGE
The client utilized a traditional network
system that was powered by the battery, which distributed data through the LTE
network. Each transmission was costly and the batteries had gone fast.
SOLUTION
DataObrii used a data-transmitter unit or
‘sensors package’ (DTU or SP), which is a separate device with a self-contained
power battery supply charged by the built-in solar panel. DTU (SP) is connected to a base station (BS)
via the communication channel, which is organized using LoRa technology. The
base station has access to the Internet. The BS exercises general control over
the DTU (SP). After receiving the information, it displays a confirmation of
data acknowledgement and, if necessary, issues new settings to the DTU (SP) for
the collection of information. The BS sends the received information to the
server. A user communicates with the server via the HTTPS protocol. With
administrator rights, he can change the settings of both the BS and individual
DTUs (SPs).
RESULTS & ADVANTAGES
The advantages of the implemented solution are
obvious. Here are a few facts that confirm this:
- the wider coverage range (6 km for urban and 15
km for suburban areas); - less power consumption, so the battery lasts
for a longer duration (1–5 years without recharging, depending on the data
rate); - LoRa technology uses solar panels for
recharging and works autonomously; - the system uses 433 MHz and the widest band for
signal transmission, which provides the greatest sensitivity at a fairly low
communication speed; - the developed solution provides data
transmission at speeds of up to 2 seconds.
TECHNOLOGIES
Data-transmitter unit or “sensors package” (DTU
or SP) that includes sensors of air humidity, temperature and lighting, CO2,
GPS, motion, air, and soil pollution.
