AirTo monitors air quality entirely on your local WiFi network. No cloud. No subscription. No data leaving your home — unless you choose to share it with the world.
Everything runs on your ESP32. Your data never touches the internet — unless you decide to contribute to the global community map.
ENS160 + BME680 on a single I²C bus. All signal processing on-chip. Readings every 5 seconds, stored locally for months.
No app needed. The LED bleeds through a 0.6mm PETG diffuser printed on a Bambu A1 Mini and morphs as conditions change.
Toggle one switch and your hourly averages join a free, open air quality dataset — anonymously, at city-level precision. Every reading visible on a live world map anyone can access.
400mAh LiPo with XIAO's built-in BMS. Deep sleep between readings extends battery life dramatically. Auto-switches modes when USB-C is connected.
Built in the open, shipping step by step. Here's the countdown to what's next.
Real PCBs I've designed and fabricated — custom 2-layer boards with ESP32, LoRa, mmWave radar, and solar harvesting. Tap any board to zoom in.
Real boards fabricated through Seeed Studio Fusion — and projects Seeed Studio featured on their own channel.
Electronics maker and open source hardware creator with 186 published projects on Hackster.io. Building AirTo to make indoor air quality monitoring accessible, private, and open to everyone.
