摘要

In the case of a method for transmission of a sensor data value of a rfid - day (100) to a rfid - receiving device (1), the steps of: generating an rfid - signal (rs) with the aid of the rfid - tags (100), wherein the rfid - signal (rs) is a rfid - signal amplitude and a rfid - signal frequency; detecting the rfid - signal with the aid of one of the rfid - receiving device (1) associated antenna device (4); determining the rfid - signal frequency with the aid of a programmable digital signal processor (6); and detecting a sensor data value in a function of the determined rfid - signal frequency with the aid of a digital evaluation device (10), wherein a respective rfid - signal frequency a respective sensor data value is associated with. A rfid - receiving device (1) for receiving a sensor data value of a rfid - day (100) comprises: a non-destructively to - and other antenna device (4) for receiving a rfid - signal (rs), which is a rfid - signal amplitude and a rfid - signal frequency; a programmable digital signal processor (6) for determining the rfid - signal frequency; and a digital evaluation device (10), which is adapted to the determined rfid - signal frequency to be assigned to a respective sensor data value.
