Sistema de telemetria para veículos de competição Baja baseado em tecnologia de comunicação LoRa

Abstract

Telemetry allows us to monitor a system in real time. On motorsports, it can be used to monitor the condition of the variety of systems that ensure the correct operation of the vehicle, like the breaking, suspension, engine and steering wheel systems. This allows the team to be able to detect problems during tests runs, practices and competitions, ensuring the safety of both the pilot and the car. The aim of this work is to design a telemetry system for Baja vehicles. To achieve this, it was used the LoRa communication technology, which offers long range and low energy consumption, making it ideal for this type of application. Additionally, three different LoRa communication systems were compared using the LoRa module E220-900T220D, as well as the SX1262 and SX1276 modules present in the Esp32 Heltec Wifi Lora 32 V1 and V3 development boards. Lastly, the Esp32 WROOM DevKit V1 board was used for reading the sensors embedded in the vehicle.
