A brief update on what we are currently working with:
smaller size – the newer versions of our system are sub-matchbox size.
better sensors – a major challenge and an issue we will get back to: most Citizen Science projects in the field of Air Quality face limits of sensitivity. While there are plenty of different sensors available and in use, most lack an order of magnitude or more in sensitivity. We thus have focussed on testing a variety of low- to mid-cost sensors. Please standby for results.
network – in addition to the well-proven and stable Bluetooth-GSM/3G version, we are planning a LoRa connected version of our system.
Measuring and Mapping of Air Quality by Bike - A PITLab project:
a clip-on for bicycles that measures different kinds of gas (e.g. carbon dioxide, ozone, nitrogen dioxide, particulate matter)
as well as temperature and humidity, and potentially many other environmental and urban properties.
The sensors in the clip-on send info to your Android phone, and information from both your phone (time and location)
and the sensors are sent to our database.
The gathered information can then be shown on a map e.g. Google Maps or OpenStreetMap.
The bAIR system is based on earlier projects at ITU, like http://noxdroid.org (2011)
and the great work done over at http://aircasting.org
