To build your very own IoT rain checking system, you will need a Raspberry Pi 3 Model B, a DHT11 Temperature & Humidity Sensor (4 pins), and a raindrop sensing board, which can be purchased for ...

The Raspberry Pi weather station uses two sensors in the form of the DHT11 Humiture sensor and the BMP280 Barometer, code has been modified from the Sunfounder’s GitHub repository.

The project is completely open source and based on a Raspberry Pi base station which connects to ESP32 based sensor nodes and online services to nicely present the data on a 7″ touch screen display.

This is just one course that will have you creating your own projects, and in this Raspberry Pi 4 essentials focus, you’ll explore using LEDs, switches, DHT11 sensors, and more. Getting Started ...
