Development of a stand alone monitoring system (S.A.MO.S.)

Environmental monitoring is nowadays a common instrumentation application, not only in cases where scientific information is needed, but also for pollution control and development planning of certain sensitive areas. This paper describes the development of a standalone monitoring system (S.A.MO.S.) which is actually a complete monitoring station for environmental measurements in rivers, lakes, lagoons and other sensitive eco-systems. S.A.MO.S. is capable of performing scheduled measurements by sensors or other independent electronic measuring instruments, and stores data locally in a memory module. Measurement data may then be transferred to a PC system for further analysis either by using a cellular phone network or via a UHF transceiver. Validation of measurements is achieved by the system´s self check control and warning signals can be sent to authorized personnel in case of errors. The basic features and the configuration of this system are presented in this work
