Environmental monitoring system based on an Open Source Platform and the Internet of Things for a building energy retrofit

摘要

This paper deals with the design and development of a low cost building environmental monitoring system, and it is based on Open Source Platforms and on the Internet of Things. To achieve this aim, a wireless micro-controller with attached sensors has been used to collect the environmental data. The information obtained from the sensors is collected and stored in a flash memory card, and simultaneously is sent via WiFi to the cloud. This data is stored in an online spreadsheet, which permits us to access the information in real time.
