The goal of this MQP was to design and implement a hand-held DC Digital Voltmeter (DVM) with wireless capabilities. Some of the specifications we sought to achieve in our final device were 5-digit voltage readings, 0.1% accuracy and approximately 100m wireless range. By implementing this DVM, we are showcasing the capabilities of some of the Analog Devices Inc integrated circuits namely the AD7799 and ADUC845. The AD7799, consisting of a 24 bit Sigma-Delta ADC with an on chip IN-AMP and 3- differential inputs, serves as a perfect voltmeter front-end in our design, the ADUC 845, a Micro-Controller, serves as the brain for the system. Whereas, a windows application designed in C# serves as the visual user interface for our system.
