Portable Weather Station
A very small portable weather station that displays temperature (in C and F), atmospheric pressure (mbar), and location (latitude and longitude). This is an open-source project; all software and 3D printed parts are available on my GitHub!
Updates will periodically be posted on this page. GitHub houses all software, 3D printer files, and data processing.
Version One
Adafruit Feather RP2040 Adalogger: Data logger and micro-controller with attached fan and STEMMA QT port
BMP390: ±3 Pascals (about ±0.25 meters)
SHT45: ΔRH = ±1.0 %RH, ΔT = ±0.1 °C
