Abstract

Currently there are many sensors that require an interface that helps communicate the analog to the digital world. At the same time preside using components such as A / D converters, amplifiers, among others, to help increase the output voltage level of the sensors and this is very small, ignore it increases its size, cost and complexity because of the need to correct problems prior to this communication. Taking into account this option proposes the design and implementation of a pressure gauge based on a direct digital interface sensor-microcontroller without the need for amplifiers or converters A / D, thus achieving a reduction in materials and cost. The type of research undertaken for this work was experimental, which allowed for different tests to calibrate and optimize their performance, thus obtaining an almost linear measuring system, since the variable pressure pattern is pretty close to the variable pressure obtained with the transmitter, which has a measuring range of [0,2 a 1,0] psi.
