Weather Station Design Using IoT Platform Based On Arduino Mega

Weather stations are built for the purpose of collecting quantitative data about the weather conditions of a place. Monitoring weather conditions in an environment today is considered to be very important because of the uncertain weather changes every day. This research tries to make weather station which can be accessed through website by using IoT platform. Users can know the weather changes in an area without the need to come to the area. This design uses Arduino Mega 2560 as a microcontroller. The measured weather parameters include temperature and humidity using DHT-22 sensors, rain detection using FC-37 rain sensor, and air pressure using BMP180 sensor. Air pressure measurement results are used to predict the weather. The measurement results of all sensors are stored in SD Card and displayed on TFT LCD 2.2 `and website using ESP8266 wifi module. In this research, the difference of measurement result with PCE-THB 40 module with an average error of 3.74% for temperature, 2.14% for air humidity and 0.32% hPa for air pressure.
