line (str) – A line of comma separated telemetry, each of the format CXX=XXXX.XXX

Returns:

output – A list of floats containing the temperature telemetry as measured by the sensor. The length of the output list is the same as the number of channels. If a channel is disconnected (its value will be DISCONNECTED_VALUE) or if a channel is missing because the connection to the sensor is established mid output, then the value gets replaced by np.nan.
