Abstract

This project uses an IDAC-1 board to sample the water level of a plexiglas column and to control its level. The level is measured by a pressure sensor and the control is performed by ON-OFF valves. Data are passed to a main computer and Internet is the transport media. The protocol used in this project is UDP/IP. The water pressure is sampled as potential difference on an A/D converter integrated on the IDAC-1. The controlling computer through the Internet acting as client asks for the pressure (water level) and IDAC-1 responds as server with the 10-bit resolution. To control the water level the IDAC-1 digital outputs through the two relays operate on the inlet and outlet valves. So, the water level can be controlled from anywhere in the World Wide Web (www).
