WHY?? Large number of different dataloggers Different software for each Different energy sources Different serial cables But... the worst of all problems was... Different initializations Tell Cintia that lost data

Coastal Environmental Monitoring Station E.M.A.C. One of the key problems of the coastal marine environmental research is the lack of environmental information continuously to establish the conditions at each site and identify possible management programs and environmental management. The Coastal Environmental Monitoring Station (EMAC) allows developed precisely to solve in an efficient and integrated these problems at a totally acceptable within the budget of public and private bodies (municipalities, provinces, ports, marinas, etc.).., Research groups on these issues and environmental consultants. The heart of the system is a multifunctional datalogger which is capable of accepting multiple sensors (9 simultaneously), which are shaped by their robust software.
