The Making Sense project is funded by the European Commission and has the mission to make advances and experiments in participatory sensing. According to making-sense.eu
Making Sense aims to explore how open source software, open source hardware, digital maker practices and open design can be effectively used by local communities to fabricate their own sensing tools, make sense of their environments and address pressing environmental problems in air, water, soil and sound pollution.
The project runs between 2015 and 2017.
The website provides an excellent Making Sense Toolkit of materials and methods for planning and implementing participatory sensing campaigns.
