A sensor structure is disclosed, notably for a harsh environment in a motor vehicle. The sensor includes a sensor body having, at one end, an element sensitive to the quantity to be measured in the harsh environment and, at another end, a circuit for connecting it, placed outside the harsh environment, physically separated from each other, connected by means for transmitting data without a connection, and between which means are provided that are permeable to data, for protecting the connecting circuit from the environment.

A sensor structure notably for a harsh environment in a motor vehicle is disclosed. The sensor structure has a sensor body () having at one end an element () sensitive to the quantity to be measured in the harsh environment and at another end a connection circuit () for the latter, placed away from the harsh environment, and physically separated from one another. The sensor structure is connected by means for transmitting information by carrier current on an electrical conductor () of the sensor with which the sensitive element and the connection circuit are associated by wireless coupling means and between which are provided means () for protecting the connection circuit from the environment.
