Citizen Science and the Tonga Eruption #Science #Tonga
A number of people heard about the Tongan volcano eruption and grabbed their Raspberry Pi and pressure sensors and recorded the pressure wave that swept around the planet.
Köln-Wetter posts: “Overview of Pressure of the volcano eruption in Tonga for Cologne. Shown: change in air pressure per 10 minutes.” (graph above)
Claudio Kuenzler posts: “Just looked that up, and to my huge surprise, even my small Bosch Adafruit BME680 sensor, connected to a Raspberry Pi 3B+ was able to catch the Tonga explosion wave!!! Stored in an Influx DB, graphs made with grafana.”
Sandy Macdonald posts: “The Tonga volcanic eruption pressure shockwave measured on a hastily set up Pimoroni BME280 sensor and Raspberry Pi in York, UK. That’s 16,270 km away, and taking 14h 20m to get here gives a speed of 1,135 km/h or 315 m/s!”

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.
