The FreeStation initiative uses open source hardware, open source software and open source 3-D printing technology to build and deploy reliable automatic weather stations with the lowest cost and easiest build possible.  

The FreeStations are designed to make reliable, detailed and local climate data more accessible in areas that may have little local financial and technical capacity for the collection of such data.  The FreeSensor initiative designs a variety of open source environmental monitoring sensors from soil moisture probes, through meteorological sensors to wildlife cameras.

As the names imply, these stations and sensors are being made available to relevant organisations (schools, local government, NGOs) free of charge and the designs are open source so anyone can build them.   The collected data is uploaded to the servers and thereby contributes to the temporal and spatial detail of data available in widely used tools such as WaterWorld.  A variety of stations and sensors are available.   The FreeStation and Freesensor concepts have the potential to fundamentally change the local information base available to scientists, NGOs, farmers and water resource managers, whilst crowdsourcing real-time, ground-based environmental data globally.  Combining these data with the vast satellite-derived archives in WaterWorld and other tools, more sophisticated and locally-relevant policy and decision making support can be provided.
