A practical, easy-to-use data acquisition device has been developed for use in civil and envirionmental engineering applications. It uses the PC parallel port for the acquisition and data transfer and is simple enough to be setup and run in laboratory and field experiment conditions. The usual limitations of data storage capacity of several data loggers was solved by using PC resources. Also versatile programming capability using high level languages of the PC programming environment such as C and Visual Basic enables the data acquisition device to be configured as a general and practical data acquisition system. An example of effective uses of the device is. provided for the water environment measurement at the Bangwha bridge construction site. The in site. test proved the device to be practical in civil and environmental engineering applications.
