RuuviTag is a Bluetooth sensor that monitors environmental conditions and sends the data directly to your mobile device. The Ruuvi Station mobile app allows you to view real-time accurate measurements and historical graphs. The app also provides customisable alerts to notify you of critical conditions, such as a melting freezer, excessively high bedroom temperatures that could disrupt sleep, or elevated humidity levels in your basement.

Most common questions
What is a wireless Bluetooth sensor?
Wireless Bluetooth Sensor beacons are small transmitters that broadcast environmental data signals to close portable devices using Bluetooth Low Energy technology. RuuviTag is a wireless Bluetooth sensor that measures temperature, air humidity, air pressure and movement.
How do you use a wireless Bluetooth sensor?
You can read live measurements and historical data directly on your smartphone using wireless Bluetooth connection. It’s not necessary to pair sensor to mobile phone. Ruuvi has a mobile app for Android and iOS.
What is the Bluetooth range?
Ruuvi sensors send data packages via Bluetooth to your mobile device. Thanks to optimized sensor antenna design, in perfect conditions without any obstacle, the Bluetooth range is up to 200 meters, which is way more than that regular Bluetooth devices.
Please keep in mind that any obstacle, especially metal enclosures, concrete walls, or proximity of water will lower the range.
Using Ruuvi sensors + Ruuvi Gateway
The sensors send the same data packages as above with the same emission power. However, the reception antenna is way better on the Ruuvi Gateway than on a regular mobile device. The highest range ever recorded, in optimal conditions, between the Gateway and the sensors is a vertiginous 2000 meters!
The Ruuvi Gateway shares then data to the cloud service and the sensor readings are then retrievable from anywhere in the world as long as you have an internet connection.
How do the Ruuvi products actually work?
The Ruuvi product portfolio is made of:
Ruuvi sensors
The Ruuvi sensors measure air temperature, humidity, pressure, and acceleration, depending on the models. More precise specifications are provided on the product page. They send the data via Bluetooth either to the Ruuvi Gateway or to the Ruuvi Station mobile app.
Ruuvi Station App
The Ruuvi Station app can be downloaded for free both from the Play Store (Android) and the App Store (iOS). It displays the measurements received from the Sensors. In the app, it is possible to read history graphs, set alerts with customizable parameters, and much more!
A web interface is also available when using our cloud service.
Ruuvi Gateway
The Gateway is our solution for remote monitoring, check how to it works on this page.
Accessories
You will also find all the accessories that you might need from stands to replacement batteries in the “all products” section of our website.
What are the operating conditions of the Ruuvi sensors?
Temperature
Electronics of the Ruuvi sensors can support temperatures between -40°C (-40°F) and +85°C (+185°F). However, the market standard CR2477 batteries’ operation range is usually between -20°C (-4°F) and +70°C (+158°F). Do not exceed these temperatures without shopping our custom made wide-range battery, which is designed to operate with the same limits as the electronics of the sensors.
Dust & Water
All the sensors are resistant to dust and moisture. Some of the sensors are IP67 certified (water-resistant) and some are IP68 or IP69K certified (waterproof). See the specific certifications for each sensor on the product page. Please keep in mind that water lowers drastically the range of the sensors.
How to monitor the Ruuvi sensors remotely?
The Ruuvi sensors can be monitored with just a mobile device and the Ruuvi Station app within the Bluetooth range. If you want to monitor conditions from further, you’ll need our Ruuvi Gateway product.
The Gateway is connected to the internet and listens to sensors with a higher sensitivity than a regular mobile device. The test results talk by themselves: up to 2000 meters between the Gateway and the sensors, compared to 200 meters between a mobile device and the sensors (test realized in optimal conditions without any obstacle).
Then, the Gateway shares the data to our cloud service. The sensor measurements are then retrievable, either from the mobile app or our web interface from anywhere in the world as long as you have an internet connection.

With RuuviTag you can measure and respond to changes in air humidity in real-time. Range: 0-95%.
"Avoided water damage"
I had a RuuviTag in my boiler room. One day I noticed increased air humidity levels and went to see what was going on. Found a leaking water pipe
