This research project is the design of a simple microcontroller based thermocouple gauge. A thermocouple gauge is a pressure meter that measures low vacuum of rough pumps. This is an important piece of equipment for any investigation that requires use of a vacuum pump. These investigations include supersonic gas expansions into vacuum to study gas clustering and atomic or molecular laser spectroscopy in which the sample is a vapor within a vacuum. Unfortunately, gauges are expensive to purchase so this project will provide a low cost, accurate and effective replacement. A thermocouple gauge works by measuring the temperature of an internal heater. The heart of this gauge will be Cypress PSoC 4 mixed signal microcontroller. The microcontroller will measure the internal temperature and to also run the heater itself. I will present my development of the meter.
