Electronic Thesis and Dissertation Repository
Industrial pilot projects and the automation of experiments often rely on expensive and proprietary electronic hardware, known as supervisory control and data acquisition (SCADA) systems, to control and monitor areas of their processes. The Broadly Reconfigurable and Expandable Automation Device (BREAD) framework was created to address the need for inexpensive SCADA systems. New BREAD Slices were designed and compared to commercial heating, motor, pump, and pH controllers, exceeding all in functionality and cost. In each case, the decreased accuracy of the BREAD controller had little impact on the final products but greatly reduced the cost of the system. The modularity …

Electronic Thesis and Dissertation Repository
A typical sensor consists of a sensing element and a transmitter. The major functions of a transmitter are limited to data acquisition and communication. The recently developed transmitters with ‘smart’ functions have been focused on easy setup/maintenance of the transmitter itself such as self-calibration and self-configuration. Recognizing the growing computational capabilities of microcontroller units (MCUs) used in these transmitters and underutilized computational resources, this thesis investigates the feasibility of adding additional functionalities to a transmitter to make it ‘smart’ without modifying its foot-print, nor adding supplementary hardware. Hence, a smart sensor is defined as sensing elements combined with a smart …
