This is attached to a 7-inch official Raspberry Pi touchscreen running a clean user interface that he created using the GUI framework Tkinter. The Arduino Uno is used to gather information from the sensors at set intervals before transmitting the data wirelessly to a Raspberry Pi 4 located inside his house. He wanted the latter to communicate with an exterior module based on an Arduino Uno, so he headed online to research and troubleshoot his way through and eventually got the two to talk to each other. “I was very familiar with NRF24L01 transceiver modules, so I picked this.”Įven so, Çağan had never used this transceiver module with Raspberry Pi before. By using wireless communication, he could dispense with wires. “The most important thing was separating the inside and outside modules because, in the previous iteration, the inside module – the Arduino and the screen – had to be placed near the window so that the cables would reach the exterior sensors,” he explains. He also wanted to present the information more clearly. To start with, Çağan wanted to expand the functionality of the weather station by adding wind speed to the temperature, humidity, and air pressure sensors of the original. With a lot of CPU muscle in the background, it was a win for bringing my project alive again.” Inside and outside “I could use fancy graphics if I wanted and also be far less conservative about my programming thanks to being able to use a massive microSD card as a storage medium.

“I couldn’t add functions to it because of the 32kB of code memory, and I wanted to include an early warning system when the air pressure suddenly dropped, which mostly means it’s going to rain or snow.”Ĭue Raspberry Pi, with the advantage of being able to show the results on a large and easily readable screen. “It was a neat project, but I hit the limitations of Arduino,” Çağan continues. That version had outdoor sensors hooked up to the Arduino using long cables and the values were displayed on a small Nokia 5110 screen. “Where I used to live, the weather was often unpredictable and I wanted to know the forecast so I could dress accordingly just by glancing at a screen.” “The original was made using an Arduino Uno when I just starting to learn electronics and programming,” he recalls. In fact, he’s developed two weather stations – the first being five years ago. He has also been making tutorial and DIY videos on his YouTube channel about hobby electronics and programming in his spare time. Çağan Çelik is a full-time hardware editor on a Turkish technology magazine. As luck would have it, Çağan Çelik has created a weather station using a fan and spoons.
