From: Assessment of aerosol persistence in ICUs via low-cost sensor network and zonal models
Distributed low-cost sensor network gathers time and space-resolved aerosol information. The data is transmitted to a cloud server, displayed in near real-time, and saved on the SD card. Left: Schematic of typical room layout and sensor positions. The black square represents the location of the particle generation source. Right: Photograph of the sensors in the ICU.
