Having created a few projects with the Arduino I wanted to experiment with the Raspberry Pi Pico as it can also run off a 3.7v battery and has a larger internal memory so offers the ability to create more complex projects.
This project is an evolution of my project “Temp and Humidity Monitor with Graphs and Battery Monitor”. I have added a BMP180 pressure and temperature module and only use the DHT11 for humidity as the BMP180 is more accurate for temperature. With the addition of monitoring pressure, I could also add a weather forecast based on the Zambretti Forecaster model.
