Abstract
The paper presents an application that involves the real-time acquisition of four parameters: temperature, relative humidity, pressure and light intensity. Several sensors are used that acquire these values (DHT11- temperature and relative humidity, BMP180 - pressure, BH1750 – light intensity) connected to an Arduino Uno development board equipped with the Atmega328 microcontroller, using digital and analog pins. The display of information is done on a monochrome screen attached to the Arduino board. The developed weather station is capable of measuring these four environmental parameters and providing readings at 5-minute intervals. Weather stations can be used in a variety of locations and domains from meteorology and weather monitoring, to agriculture, scientific research, navigation and aviation, or renewable energy industry. The weather stations can provide useful information on different weather parameters which is essential for providing accurate weather forecasts and monitoring climate changes, for optimizing the performance of energy installations and forecasting energy production.
