Ruuvi Climate Sensor, Dry

Dry rooms stay healthy rooms when you can see the numbers. The Ruuvi Dry watches temperature and humidity around the clock: in the bedroom where you sleep, the pantry where you store a season of food, the shop where your lumber acclimates. One glance at the app tells you whether the air is doing what it should.

Inside the rugged Finnish-built shell is a laboratory-grade temperature sensor, factory-tested against NIST-traceable references, a humidity sensor accurate to two percent, and a barometric pressure sensor. It reads from -40 to 185 °F, with humidity shown as percent, dew point, or absolute moisture, and pressure that tells you which way the weather is turning before you feel it.

Readings stream to the free Ruuvi Station app over Bluetooth: live numbers, ten days of history, and alerts that warn you before damp becomes damage. Add a gateway later and it reports to the cloud from anywhere. The coin battery is included, lasts one to two years, and swaps in seconds.
