RuuviTag Pro 2-in-1 Waterproof Sensor

Waterproof, submersible environmental sensor for harsh conditions

The RuuviTag Pro 2-in-1 is built for extreme environments. Fully sealed with an IP68/IP69K enclosure, it measures temperature and motion, making it perfect for monitoring wet locations like bilge compartments, lazarettes, and gear lockers. With zero openings and a fully encapsulated design, it’s ready for splash zones and brief immersion (it is not intended for continuous submersion). It broadcasts over Bluetooth with no pairing, so a Victron Cerbo GX or other GX device reads its temperature directly over Bluetooth, and it also works with the free Ruuvi Station app, the Ruuvi Gateway, and Home Assistant.
