Abstract
A sensor device and a communication method are provided. The sensor includes a microcontroller unit, and a receiver electrically connected to the microcontroller unit and configured to receive at least one communication signal. The receiver includes a magnetic sensor configured to detect a modulated electromagnetic carrier signal as a first communication signal and output an encoded measurement signal based on the detected modulated electromagnetic carrier signal. The sensor device further includes a demodulator configured to convert the encoded measurement signal into a data signal and output the data signal to the microcontroller unit.
