ABSTRACT

Data acquisition is the process of gathering information on a phenomenon by acquiring data on one or more variables. An example of a data acquisition process is recording the variation of ambient temperature as a function of time. For automated data acquisition, you need suitable sensors and associated hardware that can connect the sensor(s) to a host computer. You also need the software necessary to transport and translate the data from the sensor(s) to the host. This book is not about sensors or associated hardware, but it is about ways you can connect a sensor and its hardware to a PC using an efficient and unconventional interface: the parallel port.
