I need to decode a dataframe from a tire pressure sensor that transmits data via a 433.92 MHz RF signal using FSK modulation. I assume that the sensor uses Manchester encoding. Then the data should be interfaced with CAN bus.
But I have done a lot of research but the issue is I am not sure what the data TPMS sensors are transmitting. Thus, I need a way to read the data via a receiver with an arduino.
jremington:
Google "decode tire pressure sensors" for several discussions.
Showed that you can decode the signals even if you don't know what the data frame looks like.
The first link and video covers that but with tools other than an Arduino.
Agreed, given a number different examples of a signal, it is often possible to deduce what the data frame "looks like". One general approach is described here.
That tire pressure is involved will be a strong hint.
