Wireless Weather Station Using Arduino Mega and Arduino Nano

The study aims for the development of a wireless weather station composed of two modules, the outdoor module that takes the temperature and humidity from the environment through the DHT22 sensor and transmits the information through the n24RFL01+ communication module to the indoor module. The indoor module takes the temperature and humidity from the environment and displays it on a 3.5” TFT display along with the information received from the outdoor module, also the date and time are displayed. The development boards used for the weather station are Arduino Mega 2560 for the indoor module and Arduino Nano for the outdoor module. The n24RFL01+ wireless communication module, depending on the model, can transmit data at a distance of 800+ m and the DHT22 sensor is very accurate. The programming code used for the development of the weather station is made in Arduino IDE. Arduino IDE is an open-source software that is used to write and upload code to the Arduino developing boards.
