NOVELTY - The sensor system includes a substrate (15), on which several sensor elements (10) are mounted. The sensor elements each produce electrical signals based on the thermal radiation they receive. A self-test device such as a heating resistor (53) produces heat by which the sensor elements are warmed. DETAILED DESCRIPTION - A method of manufacturing a substrate for the sensor system is also claimed. USE - For infrared radiation detection using, e.g. a thermopile. For use in motor vehicle, in which all sensors are tested when the vehicle is started up. ADVANTAGE - The system operates reliably. DESCRIPTION OF DRAWING(S) - The drawing shows several embodiments of the invention in combination. sensor elements (10); substrate (15); heating resistor (53).
