Abstract

A method for transmitting data from a sensor to a receiver by means of an analog interface, whereby, during a first period of time, the sensor transmits identifier data for identifying the type of the sensor and/or for identifying the type of a component associated with the sensor, and measurement signals of the sensor are only transmitted after the first period of time. In this context, it is also provided that the transmission of the identifier data serves to identify a specific sensor from a group of multiple sensors and/or a specific component that is associated with the sensor from a group of multiple components, whereby the multiple sensors of the appertaining group and/or the multiple components of the appertaining group have mechanically identical interfaces and consequently can fundamentally be employed alternatingly. A method according to the invention is advantageously suitable, among other things, for transmitting data from a cylinder pressure sensor—which is especially integrated into a glow plug of an internal combustion engine—to a receiver, whereby this receiver can especially be integrated into a control unit, for instance, an engine control unit of the internal combustion engine. With such a method according to the invention, before measurement signals of the cylinder pressure sensor are transmitted, the engine control unit of the internal combustion engine can advantageously identify whether a defined, selected cylinder pressure sensor, and particularly a defined selected glow plug with an integrated cylinder pressure sensor, is also actually installed in the internal combustion engine.
