The Density sensor uses infrared lasers to accurately count humans entering and exiting the doorway where it is installed. Every second, the lasers generate tens of thousands of accurate depth measurements. The device then applies machine learning algorithms—developed by Density specifically to pinpoint human movement—-to process these measurements in real time. The device sends count data—+1 for an entrance, -1 for an exit—to Density’s cloud service, where it’s then available via Dashboard and API.
