Abstract
The STELLA-1.2 base unit includes a microcontroller, GPS, BME280 (temperature, pressure, humidity), and rotary control with display. Sensor modules include: • Spectrometer: 18-band VNIR from 410–940nm, UV, light, IR, lidar • Air Quality: CO2 (SCD-40), PM2.5/PM10 (PMSA003I), methane • Expandability: More modules via magnetic couplers and CircuitPython menu additions STELLA-1.2 is an innovative low-cost, modular, open-source sensor suite designed for environmental and spectral analysis. The platform supports interchangeable sensor cartridges that attach magnetically to a central data-logging base unit, enabling users to collect air quality, spectral, and geospatial data in a flexible and accessible manner. Designed with affordability and accessibility in mind, STELLA-1.2 is built from commercially available components and can be assembled using 3D-printed snap-together parts without fasteners.
