Rancang Bangun Sistem Alat Ukur Tekanan Udara pada Tangki Uap Air Berbasis Arduino Nano Menggunakan SD Card Module Data Logger

Abstract

Steam water tank is a pressurized closed vessel, where water is converted into steam by applying heat (heat). Air pressure measurement is very important to do so as to get a good reference value. Measurement as the act of comparing something with a certain unit of measurement so that it becomes quantitative. Inside a specific variable. The test will be carried out in a vacuum chamber of stainlees and given a sample of hot water with a different temperature. The working system on this tool is a system of conducting air pressure and temperaturewhich is in the steam tank. The air pressure and the initial temperature in the steam station are measured. The working principle of the sensor takes the sensor data and then sends the data serialized and sends the sensor level value to the slave with SPI communication and in the process. Then process the sensor data from the BMP 180 sensor with an analog output. Then the sensor measures the air pressure and temperature in the tank that contains water vapor, If the sensor is legible then YES. Then the air pressure and temperature data will be stored in memory with the sd card data logger connection module.Then the sensor data is played on the LCD. And re-read the data in realtime. From the results of measuring the measurement value at the beginning of the test is with an air pressure of 1.96 Pa and a temperature of 47.00 C. After 10 minutes the air pressure value is 1.87 Pa and the temperature is 43.20 C. The latest measurement of the air pressure value is1.77 Pa and the temperature is 42.10 C. With this the tool system can be implemented.
