Design Implementation of Integrated Sensors for Weather Detection and Monitoring Systems

Abstract

Data of weather are important to obtain as it yields some benefits from knowing it. One of them being evacuation from disasters. For example, if there is a typhoon, we know the direction where it is heading. Another one being helping the work of weather forecasts. Data taken can be used to forecast if temperature in the next days will increase or decrease, and if the weather changes. To obtain those data, we need sensors. Most sensors cannot measure all weather data individually, which means that to measure more of those data, those sensors must be combined. This work aims to assemble sensors and integrate them into a prototype that can obtain weather data parameters. The prototype is then used to get data through data obtaining process, so that it may be used to analyze the weather. This study created an integrated sensor prototype with Arduino as its microcontroller. Sensors such as DHT-11, wind speed sensor, and wind direction sensor are integrated so that they may capture parameters at the same time. To make the prototype easier to use, LCD display is used to show the data when the prototype is in use, and the data is also stored in SD card for analysis purposes. Parameters were taken in 2 locations, analyzed with tables and graph, and also compared with results of another study to see if the data makes sense. The prototype was successfully built and easy to use. The temperature difference is only 3.6-4.1 C, humidity difference being 1%, and the wind direction difference being 1.01 m/s. Considering weather-atlas taking data for the whole day as opposed to this prototype, the provided data makes sense.
