Abstract: The invention relates to a sensor having a filter arrangement, downstream of which there is arranged a detector arrangement, and an evaluating device which is connected to the detector arrangement, the filter arrangement has at least a first filter, the suspect filter, which is configured as a band pass filter allowing the passage of a first predetermined band, the suspect band, at least one second filter, the reference filter(s), which is configured as band pass filters allowing the passage of a second predetermined band(s), the reference band(s), and where the detector arrangement has at least one detector associated with the at least one of the filters. The sensor uses the band pass filters to measure the temperature of an emitting source. The sensor with advantage could be utilized within the IR band, and could advantageously be used to detect CO2.

Abstract: An IR sensor (1), especially a CO2 sensor, is described, having a filter arrangement (6), downstream of which there is arranged a detector arrangement (7), and an evaluating device (8) which is connected to the detector arrangement (7), the filter arrangement (6) having a first filter (9) and a second filter (10), which are configured as bandpass filters and each have a passband and of which the first filter (9) allows passage of a predetermined IR band and the second filter (10) does not, and the detector arrangement having two detectors (14, 15), each of which is associated with a filter (9, 10). The objective is to simplify the use of such an IR sensor. For that purpose, the passband of one filter (10) is arranged within the passband of the other filter (9) and the evaluating device (8) forms the difference of the signals (S1, S2) of the detectors (14, 15) and normalises it to the signal (S1) of a detector (14).
