What we do

pir sensor

PIRLABS offers measurement services to any manufacturer or user of passive infrared motion detectors. We are specialized in characterizing and visualizing the sensitivity distribution (beam pattern) of such devices. Our typical clients are manufacturer engineering divisions and security companies.

Data Visualization

top view of a beam pattern

We create the sensitivity beam pattern of your PIR motion detector by measuring the PIR sensor output signal as it responds to a moving heat source. Because the resulting beam pattern is not the result of a simulation but includes the entire optical system you will get a truly reliable insight into your product.



Results are reported to you in a standard pdf-format document or, optionally, in a custom report format designed to your specification. Quantitative data, 2D maps and 3D models may optionally be exported in industry-standard file formats including .csv, .png and .stl, other file formats are available on request. Please refer to our EXAMPLES PAGE.

We help you add value

The beam pattern information gives you a competitive advantage. You can provide your customers with more detailed information on the behaviour of your detectors, lenses and sensors. You can optimize your lens and sensor quality. You can verify that your lens supplier has provided you with accurate information. With a beam pattern you can show your customers the detection zones and the best mounting location for your motion detectors. Or, you can use the beam pattern to tune your analog or digital filters by simulating the PIR sensor's output voltage changes as reaction to different object shapes, sizes and speeds.

PIRLABS helps you to put your company in the lead!
