7 Claims

1. A method for monitoring individual exposure to air pollution, comprising:

using a plurality of air quality monitors to detect at least one air pollutant in a plurality of locations, wherein each air quality monitor comprises a RF scanner and a radar scanner;

using at least one of the plurality of air quality monitors to perform the following actions:

use the radar scanner to scan the vicinity of the air quality monitor;

use the radar scanner to detect any living humans in the vicinity of the air quality monitor;

use the radar scanner to determine the number of living humans present;

record at least one radar parameter associated with each of the living humans detected, wherein the at least one radar parameter comprises at least one of the following: shape, size, movement patterns, location;

use the RF scanner to detect any RF signals in the vicinity of the air quality monitor;

use the RF signals to identify any mobile devices in the vicinity of the air quality monitor and a distance between each mobile device and the air quality monitor;

analyze the at least one radar parameter associated with each of the living humans detected and the mobile devices identified by the RF scanner to determine which mobile devices are carried by which of the living humans;

for each of the living humans where a mobile device is present, combine the at least one radar parameter and the mobile device identification to form a unique personal signature;

for each of the living humans where a mobile device is not present, use the at least one radar parameter to form a unique personal signature;

for each of the living humans where a radar parameter is not present, use the mobile device identification to form a unique personal signature;

transmitting the unique personal signature to a server;

transmitting a time stamp for the unique personal signature to the server;

using the server to compare the unique personal signature with at least one stored unique personal signature;

if the unique personal signature matches at least one stored unique personal signature, using the server to identify the person;

if the unique personal signature does not match any of the at least one stored unique personal signature, storing the unique personal signature on the server and creating an identifier for a new person with the unique personal signature;

using the server to determine entrance and exit timestamps using a first time and a second time for each person associated with a unique personal signature, wherein the first time is the time the person entered the vicinity of an air quality monitor and the second time is the time the person exited the vicinity of the air quality monitor;

using the server to calculate each person's cumulative pollutant exposure based on air pollutant data received from each air quality monitor between the first time and the second time for the person.
