Sensor.Community (https://sensor.community/en/) is a contributors driven global sensor network that creates Open Environmental Data. The network consists of over 12.000 sensors each measuring several different values, e.g. air pollution, noise or climate information such as temperatures. In this citizen science project any of us can purchase a sensor, mount it at a place of interest and share the data with the community. The typical sensor setup is very cheap (about 50,-euros).
The goal is to include citizen science projects, collect environmental data on a large scale and provide them as open data.
By implementing PIDINST we aim for higher visibility of the project and the data. Standardized sensor meta data will allow a better understanding of available measurement data and therefore support a more targeted search for measurements, which can be used in different analysis workflows. By including the citizen scientists (the owners of the sensors) in the meta data collection process (e.g. contact details), a higher identification with the community can be achieved.
The current standardization is driven by the development of the sensor firmware and the central data collection end point.
