Welcome to the next tutorial in our Raspberry Pi 4 programming course. In the previous tutorial, we learned how to automate your home with a Raspberry Pi and Bluetooth Low Energy. We found that using a Raspberry Pi 4 and Bluetooth Low Energy (BLE), users may command their household appliances from their smartphone or a web interface, and the Pi 4 will carry out the commands. This allows for a versatile and adaptable method of managing lights, thermostats, and smart plugs. However, this Internet of Things (IoT) project aims to create a real-time Raspberry Pi weather station that displays the current humidity, temperature, and pressure values via an LCD and an online server. With this arrangement, you can track the local climate from any location in the globe over the internet and see what t ...
