Abstract
The present disclosure relates to a sensor system with asynchronous data transmission, wherein the sensor system includes at least two individual sensors, each sensor having a first I/O pin and a second I/O pin. The sensor system also includes a microcontroller with a transmit pin and a receive pin, and a single-wire data line by means of which the microcontroller is configured to communicate with the individual sensors via an asynchronous data protocol. The single-wire data line runs between the transmit pin and the receive pin of the microcontroller, and the individual sensors are arranged in a daisy chain and are integrated into the single-wire data line in sequence.
