Arduino Based Anemometer: A Wind Monitoring Device

Abstract

INTRODUCTION

Approximately twenty tropical cyclones every year enters the Philippine Area of Responsibility where fifteen are typhoons and five are super typhoons (ADRC, 2008). This is because of its location along the ring of fire or typhoon belt (Wingard and Brandlin, 2013). This research study aims to develop a device that can monitor the weather and be able to measure it digitally then send the data through text message using a GSM Module.

METHODS

The device proposed wireless connectivity by using GSM Module that provides a reliable, portable and low-cost tool for the industry where it is necessary to have an environmental control on monitoring the weather. It consists of an anemometer and temperature sensor that was controlled by an Arduino microcontroller, the device was programmed in C++ programming language to send text messages when a certain range was reached in three levels. An accuracy test was used for the gathering of data to analyze the overall performance of the device.

RESULTS

The data obtained were tabulated and treated statistically to show the results of whether to accept or negate the hypotheses. The accuracy of the device is 92.5% in measuring the average wind speed and temperature; 93.3% in sending a text message with a warning; and 93.3% in alarming in three different level warning. It shows that there is a systematic error that occurred during the testing of the device. While testing the device, there was a time when the device cannot show the average wind speed and temperature in the LCD display which means it cannot read the wind speed and temperature. With these results, it can be inferred that the device can function according to its programmed task. The overall accuracy of the device after testing it based on its three parameters was 93%. Thus, reject the null and accept the alternative hypothesis.

DISCUSSIONS

In result, it was evident to say that the device was functional. Although, the results demonstrate some minor problems such as systematic errors, the device functioned according to its programmed task The device can serve as a local weather station used in times of a storm for monitoring purposes.
