Throughout time researchers have been trying to monitor air pollution and create urban pollution maps as precise as possible. This isn’t an easy task for a couple of reasons. Firstly, a lot of sensors are needed to be spread all around the city and then the researchers have to decide if the sensors will be stationary or will be mobile. Some clever and interesting projects to combat the air pollution with mobile Air Quality Monitors (AQMs) are.
The Pigeon Air Patrol
A creative way for mobile Air Quality Monitors to be spread around the city. The pigeons wear a small device with O3, VOC and NO2 sensors. While they are flying around the city or sitting on a traffic light to rest, the sensors are constantly logging air quality data. The data will be later analysed by the researchers when the pigeons return to the base. This air monitoring campaign run for 3 days only and the pigeons are now back to their normal life.

The Taxi Air Quality Monitors
This innovate idea for monitoring urban air quality was made by James Puderer. The idea is to place Air Quality Monitors on top and inside the Taxis/Cabs sign and allow them to do their normal and daily trips around the city while they are logging air quality data. Basically it is an Android Things based data logger with a host of environmental sensors, GPS, and battery. In this project he uses temperature, humidity, pressure, and air-borne particulate PM10 – PM2.5 sensors.

5th Graders Monitor Their Air Quality
We all know how busy school roads can be, especially during peak hours when parents leave and pick up their kids from schools. Definitely the air quality is very bad during that time. Some universities, colleges and organizations have decided to track the air pollution from a different perspective by giving special backpack to some of the students, backpacks with a GPS and air quality sensors. Students are responsable to carry the backpack AQM with them and monitor the air quality. Later the experts will analyze the data that the students had logged on their backpack AQM.
