Proximity Sensor System

A custom system of Bluetooth emitting beacons and signal loggers which provide an objective measure of proximity. The system can be used to help determine when someone is close to a stove or in a given area (e.g. kitchen), to help understand the drivers of exposure to air pollution.

Selected Examples of the Bluetooth Proximity Studies
