The device collects an air sample from the surrounding environment via a DC brushless fan, pulling it through custom 3D printed tubing. A video of the sample is recorded using a digital holographic imaging system, consisting of a 4.5 mW, 405 nm wavelength laser opposite a CMOS camera sensor. This raw video is then wirelessly transmitted to an external computer, where it is processed and filtered; the new filtered videos are then analyzed by a computer vision model that detects particles and returns count and size distribution data.
