Sažetak

This paper describes the components that are used in the setup of a weather station, and shows the program code and layout of the component connection. In order to function, the Arduino weather station requires several components communicating with each other and providing the user with the required parameters. The primary component is the main microcontroller, which will operate all other components. This paper uses the Arduino Uno platform, to which it is possible to connect many add-ons, such as various sensors, shields, etc. The DHT22 sensor, used to measure the temperature and humidity, is connected to the main controller. In order for these values to be seen and printed, an LCD screen is used. If the user is not able to see the values on the LCD screen, ie., if it is not near the weather station, a GPRS / GSM shield is added on the main microcontroller. Its task is to send the measured values via text message in a predefined time interval. A portable rechargeable solar battery is used to power the weather station, and therefore the weather station can be used everywhere, especially when there is sun in the sky. This paper can be used for different purposes, and with some small upgrades the efficiency is even greater. A mobile application can be designed, that will work out statistics of temperature and humidity using the values sent by the text message. By adding relays, the heating/cooling of a building can be controlled.
