Abstract

The paper presents and describes a solution for on-line, in-situ automatic cleaning and calibration of stand alone sensors that measure quantities used in the assessment of rivers and lakes water quality. The system, which was also designed to extract water samples for measurement, includes a set of pumps and electro-valves that are controlled by a microcontroller (PIC17C752) based unit. The control and primary data processing is performed by a LabVIEW Real Time controller (FP-2000) that communicates RS232 with the microcontroller based unit. The advanced data processing is made on a laptop PC that works in a Wi-Fi based network including the FP-2000.
