Sensor system for in-situ monitoring the surface waters quality of the Veleka River, Strandzha Nature Park (Bulgaria)

Monitoring the environmental status along the Veleka River (Strandzha Mtn, Bulgaria) is an essential measure for avoiding the dangers of ecological catastrophes and for preserving the unique biological diversity in this region. A system for monitoring some of the main parameters of surface waters, soils and air, as well as the sunlight levels, has been designed and initially tested. For this purpose, an automatic, remote measuring station was developed, intended for installation on the shore, near the riverbed. It has been designed not only for collecting and archiving information about the physico-chemical status of the river, but also periodically sends the data to a communication server. The developed system of several automatic measuring stations will enable us not only to analyze the current status, but also to generate an early warning in case of danger health ecosystem decline.
