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.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
