Transform Your Space with a Sleek, Retro-Inspired Air Quality Monitor
A minimalist, retro-styled air quality, humidity, and temperature sensor powered by the Raspberry Pi Pico.
Born from the #PicoBuilders contest, this project combines sleek design with smart functionality to bring you a compact, stylish way to monitor your environment.
With just a Raspberry Pi Pico, MQ135 (air quality), DHT11 (humidity/temperature) sensors, and a crisp 0.96" I2C OLED display, it delivers real-time readings at a glance.
Whether it’s perched on your desk or mounted on a wall, its clean aesthetic and easy setup make it the perfect addition to any modern space.
Simple. Elegant. Functional.
Dimensions: 75x90x50 mm

7x M2x5 screws
2x M3x10 screws
Still a work in progress.
Currently USB-powered (battery-powered planned for later).
Compact design—USB plug may move outside in v2.
Top part needs supports to print; MQ135 sensor might use hot glue instead of screws.
Assembly is simple, but a guide could be added.
