LoRa (Long Range Radio) technology can be used in a variety of telemetry and monitoring applications. Its main advantages are its range, which can reach up to 15 km, and the low power required for transmission. It's no surprise that LoRa devices are widely used to transmit information from remote units when power is limited, using long-life batteries (8-10 years).
There are several scenarios where LoRa can be used. We recently implemented a sanitation monitoring application in a mountainous region in the interior of São Paulo state, where cellular data signals are only available on the ridges adjacent to the equipment installations. Therefore, it would be impractical to implement an IoT monitoring solution using only Above-Netcellular gateways and RTUs.
The solution was to create a local LoRa network between the points, which are an average of 2 km apart, connected to a LoRa Cellular gateway for transmission via a 3G link.
All equipment and facilities were designed for the critical environment with grounding and high surge and lightning protection, in addition to battery backup, and the solution is capable of indicating in real time the failure of electrical systems involved in monitoring.
In addition to reservoir levels, we monitor pressure, pump status, temperature, current, and equipment voltages, indicating anomalies and deterioration in operating conditions with automatic triggering of procedures for the maintenance team.
Above Above-Net has extensive engineering experience in local and remote industrial network communications, enabling us to customize monitoring and telemetry solutions for any environment where communication conditions are poor. Together with Bridgemeter , our industrial IoT platform, we drastically reduce our clients' travel and maintenance costs through continuous treatment plant monitoring.
