Coming in to the new racing season our team (Pit Lizards) is looking at implementing an automatic wireless transmission system for our car's engine temperature, battery current & volts and the speed it is travelling at. These measurements would be transmitted periodically, say every 30 seconds of racing time, to the pit crew who could then use the data to advise the driver.
Do any other teams have this kind of system, and how do you do it?
Currently we are looking at using a Raspberry Pi as the computer to transmit the data along with a digital voltmeter, ammeter, thermometer and speed measuring device. So far we have found that USB ports would be the most suitable to connect the whole thing together, but we're not sure about wiring it all up or programming the devices correctly to transmit.
Any advice would be appreciated, cheers.
