Abstract

We present a general purpose internet based transducer interface module. The interface is designed to connect to the parallel port of a server. The interface is capable of reading 10 analogue inputs, setting two analogue outputs, and switching 8 digital outputs. The interface is designed to measure quasi-static quantities such as temperature and strain. The transducer interface enables the connected sensor system to be controlled, and for data collected to be accessed over the internet. The internet interface is comprised of a web page, with options to select which input to read, and which output to set. The web page, written in ASP, passes values to the parallel port interface program, written in C. The program output is then passed back to the web page to be displayed on screen. To demonstrate the operation of the web based transducer interface, two applications were demonstrated. The first was the implementation of a remote temperature control system. The temperature was monitored via the internet, and controlled by remote activation of an electric fan through the interface. A teaching and learning application was also demonstrated, based on distance learning of electronics.
