Control electronics for Chemical sensors

Abstract

his project consists in the creation of a digital control for a chemical sensor in charge of reading the temperature and keeping it close to a specific temperature (threshold temperature). To keep aspecific value of the temperature the digital control processthe information provided by the chemical sensor and indicates based on the information if the “heater”has to be heated or cooled. The document covers the description of the elements used to process the information, the detailed explanation of the data acquisition and the digital control system designed.In terms of results, the system has been tested with different input signals and with the chemical sensor and the results obtained show a good performance of the digital control
