Project Overview

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.
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.
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).
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.
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.
