RuuviTag | Versatile Bluetooth Sensor, 2-Pack
See all Happy Work giftsDescription
Designed and manufactured in Finland, RuuviTag is a compact, weather-resistant, and open-source Bluetooth sensor. It continuously measures and transmits temperature, humidity, air pressure, movement, and battery voltage every 2.5 seconds, regardless of whether a mobile app is connected. Any smartphone within Bluetooth range can receive this data.
No hub or gateway is required – all you need is a compatible Android or iOS device and the free Ruuvi Station mobile app. Setup takes just minutes, and data logging begins instantly. RuuviTag is suitable for use almost anywhere – from homes, apartments, and cottages to cold storage rooms, ceilings, and more. There is virtually no limit to the number of RuuviTags you can connect, and selecting the desired sensor in the app is easy.
The Ruuvi Station app displays real-time data from nearby sensors directly on your phone screen. You can track environmental changes, set alarms and notifications – for example, place a sensor in a sauna and get notified when your desired temperature is reached. The app also alerts you if the connection to a sensor is lost.
RuuviTag also works as a data logger, recording temperature, humidity, and air pressure data for the past 10 days, with 5-minute intervals. When your phone comes back into Bluetooth range, the data is synced to the app.
RuuviTag is also compatible with the Ruuvi Gateway, which allows you to access your sensor data from anywhere.
