Affordable remote terminal for sensor observation service

In the Internet of Things era, where the availability of data connectivity and smart devices is every day spreading more and more, the capability of acquiring sensor data through a simple, affordable and power efficient solution is a promoting factor for the collaborative creation of data set according to the Open Data philosophy. This setting is particularly fitting the agent environmental monitoring through repetitive measurement of physical-chemical parameters. This manuscript presents a new software solution for data acquisition based on a Raspberry PI terminal equipped with a thermal sensor and data connectivity at the system level. It exploits the features of the Sensor Observation Service (SOS) standard, such as the data model and the communication formats, and it assumes the availability of an SOS server to archive the data.
