Wireless telemetry system of an Off-Road vehicle

Abstract

The article presents the construction and operation principle of a wireless data transmission system read out from the CAN bus of an off-road recreational vehicle. The built-in system uses data transmission standards, through Bluetooth that allows data to be received on portable devices such as a tablet or smartphone, but it is characterized by a relatively small range. The second channel of data transmission is a radio transmitter operating on the frequency of 433MHz, which allows reception and recording of data on PCs and has a range of 1000m. The article also describes built author applications that work with the discussed device.
