Measured background noise within the laboratory environment with PIR sensor shrouded. (a) output noise voltage. (b) associated single-sided amplitude spectral responses. The red plots represent unfiltered measurements and the blue plots represents the addition of an anti-aliasing filter, inserted between the PIR sensor and ADC, having a cut-off frequency of 2.5 kHz.
