Filter och kapsling för IR-givare / Filter and installation for IR-detectors

<p>This paper describes the work done trying to diminish the noise present in the signal from an IR-detector. The project was aiming towards two different kinds of applications; heat protection and presence detection. The hypothesis was that the signal-noise ratio would decrease if a filter and a proper installation were used for the detector. Some experiments were executed to determine what kind of filter were the most suitable for each application and how these could be installed. After executing the experiments and evaluate the results we recommend to use a specific filter for each application. To install the filter over the detector we evaluated which one of gluing and taping was the best and found that tape is better to use when small amounts are desirable and gluing with silicon is better if large-scale are desired.</p>
