Air Temperature And Humidity Data Loggers Equipped with Labview and Arduino-Based Warning Systems

In the industrial world the process of measuring air temperature and humidity is a very important measurement process in the production process. But in practice in the field, the process of measuring air temperature &humidity is mostly done manually, which is done by recording which has the disadvantage of inaccurate measurement data. Recording temperature measurements that are done manually causes the product results to be not good, both in terms of quantity and quality. Related to these problems, the author took the initiative to create an alternative data logger device that is simpler, easier to integrate and relatively more affordable, without reducing the value of measurement accuracy. This data logger tool functions to monitor air temperature and humidity in real time, whose monitoring results are displayed through a system interface with the help of Labview software, Arduino Uno & DHT sensor. The final results of the trial design of the data logger tool are able to & have advantages, among others, air temperature and humidity parameters can be monitored automatically accompanied by alarm notifications, air temperature and humidity data parameters can be recorded automatically into logging data in the form of MS Excel format, and user can analyze data on air temperature and humidity parameters and the final results of the trial This air temperature & humidity data logger tool has an error rate of 0.5%.


I. INTRODUCTION
In the industrial world the process of measuring temperature is very important in a production process.However, in practice in the field, the temperature measurement process is mostly done manually, which is done by taking notes, which has the disadvantage of inaccurate measurement data.Recording temperature measurements that are done manually causes the product results to be not good, both in terms of finished results and quality.It was from this problem that the author took the initiative to make a study with the title "Design and Build a LabView-Based Temperature Data Logger System".With the hope of monitoring the temperature & humidity of the air in this system has advantages, Temperature and humidity can be monitored automatically, air temperature and humidity data can be recorded automatically into logging data in the form of MS Excel format.• Free variables

B. Product Range
In this study, the free variables are air temperature and humidity.Where is the temperature and humidity of this air that will be monitored by the application.
• Bound variables DHT11 sensor, we will monitor the temperature and humidity values of the air read from the DHT11 sensor connected to the Arduino and the values will be visualized in the form of an applied dashboard and air temperature and humidity parameters can be stored in MS Excel.

• Data Analysis Methods
The data analysis method used from this study is qualitatively discriminatory by recording the results of product tests after it is operated.Includes how to operate, how to analyze, and how to record into MS Excel.To display an alarm that is happening.The list of alarms in the data logger system is:

B. Product Test
Researchers manually tested the air temperature and humidity data logger tool system against the functions and menus of the existing data logger tool system.There are 2 items tested, namely on the software and hardware side.
The test was carried out every 5 hours without breaking, and the data was taken once every 1 hour by means of manual recording.This is done with the aim of obtaining data on the stability and resilience of the data logger system.The test of taking air temperature and humidity data was carried out for 5 hours without stopping.for the retrieval of air temperature and humidity data taken once every 10 seconds by the software.And here are the test results of the report in the form of MS Excel.From this test, the air temperature and humidity parameters are well stored in the form of MS Excel format without errors.And the air temperature and humidity report data can be used by users.The data is still in the form of raw, can be processed into pivot form and analyzed in the form of graphs.

C. Data Analysis
From the test result data of the data logger tool, the test results of hardware and software test results data are divided per experimental item.Researchers set the overall data logger tool error tolerance standard at 3%.Hardware error tolerance standard of 5%.From the data from the test results, it was found that the error rate was 0.5%, while the tolerance standard set by the researcher was 3%.It can be said that this air temperature and humidity data logger tool works well and successfully.

IV. CONCLUSION
From the research and testing of the air temperature and humidity data logger tool, it can be concluded as follows: 1.The tools and all the components needed to take the temperature and humidity of the air with the software can function properly.2. Data on temperature parameters and air resistance of alarms can be stored in the database and can be printed in the form of MS Excel.3.For installation, the control box must be placed in the room.4.This temperature and air absorption data logger tool only functions to monitor the temperature and humidity of the air, not control the temperature and humidity of the air.
