Abstract

The paper presents the architecture of a microcontroller-based multi-sensor able to measure different quantities used to characterize water quality and, at the same time, to disseminate data over the Internet. The architecture of the system includes a sensitive unit (that performs pH, temperature and turbidity measurements), a data acquisition, processing and communication unit, (16F877 microcontroller), and a RTL8019 LAN controller. The system also incorporates GSM communication capabilities in order to allow stand-alone operation in places such as river basin waters.
