Perancangan Alat Ukur Tekanan Udara dengan Menggunakan Sensor Pressure Gauge Mpx5700 Berbasis Atmega8535

Abstract

In this final project has developed an air pressure gauge to determine the air pressure in a confined space with measurement results in the form of satua psi and converted to kPa. At this along tool, a tool to help in the measurement of pressure is to use a gauge pressure sensor MPX5700 series which will then be applied using several components so that it becomes a measuring instrument. An air press will be given in the form of tools bicycle pump then the air pressure will go into the sensor. The output of the sensor will then be entered into the ADC port on Micro and converted into digital data. From the results of testing several samples above the ADC values obtained are almost close to the true value.
