Abstract
A method records and transmits data between a transmission unit that has a first antenna and a measurement module which has a sensor for recording measured variables and converts the measured variables into electric signals. Data is bi-directionally transmitted between the measurement module and the transmission unit located within the near field of the measurement module by use of a second antenna that is arranged on the measurement module. The electromagnetic energy of the signal that is applied to the second antenna is transformed and temporarily stored by a reception unit which is arranged downstream of the second antenna. The first antenna of the transmission unit is put in an inactive state at least during the time the measured variables are sensed by the measurement module or the sensors.
