Ruuvi Brings Sauna to Your Mobile

A sauna in a winter landscape

We Finns are known for our sauna culture. Saunas can be found everywhere in our Nordic country: city homes, country cottages, hotels, sports centres and gyms — even at the Finnish Parliament. It’s hardly surprising that it’s considered as one of our favourite pastime regardless of age, gender or social status. Heating a traditional sauna is almost like a ritual, a family tradition that is passed on from generation to generation.

Ruuvi, a Finnish technology company, created an environmental sensor that can be used where others fail due to high temperature and other challenges unique to saunas.

Ruuvi Station alerts you when sauna is ready

It’s late Friday at the home office. You’re pushing through your last tasks when your phone suddenly vibrates in your pocket: it’s an alert notification from Ruuvi Station app telling that the temperature inside your sauna has reached +75°C. It’s time to unwind and relax.

No more looking at the watch: RuuviTag will trigger alert on your mobile phone when sauna is ready.

Using RuuviTags is really that easy: install RuuviTag into a safe place inside a sauna, add the sensor in Ruuvi Station app and configure a temperature alert — your brand new smart sauna experience has arrived to your mobile!

Unique environmental challenges

Traditional saunas, such as the smoke sauna, can take hours of preparation before use and requires special care during the process. Dark black interior of smoke sauna is created by the soot that burning wood releases inside the room. Soot is not dirt though — it’s known to have antibacterial properties similar to charcoal. The lingering smoke aroma inside the smoke sauna makes it unmistakably unique.

But soot can spell trouble for a beacon sensor, which can be completely unprotected from the fine particles created through the burning process. RuuviTag is housed inside a protective case, which covers it from dust and other fine particulate matter, and prevents the beacon sensor to get into direct contact with water. The environmental sensor breathes through a special IP67 certified water-resistant vent sticker allowing the sensor to accurately measure the surrounding conditions.

Smoke sauna presents unique challenges for environmental sensors.

Saunas aren’t exactly friendly places for electronic devices: temperatures can typically reach 70–100°C, and temporary humidity as well as possibility to get in direct contact with water are real threats for any electronic components.

Using an environmental sensor inside a sauna requires careful planning and choosing the right one for such challenging conditions can prove difficult. Finnish RuuviTag is an excellent choice due to its temperature range (up to +85°C, when fitted with extended temperature range battery), as well as humidity and water resistance provided by its unique enclosure.

Most popular types of Finnish saunas

A traditional sauna consists of a stove, that is used to burn dry wood, and a basket of rocks, where water is thrown to increase humidity inside the room.

A smoke sauna (savusauna) is considered as the original Finnish sauna experience, and it’s known to provide a soothing and soft heat with a light smoke aroma.

Another variation of wood burning sauna, typically called as sauna with chimney (puusauna), uses a chimney on top of the stove to guide the released smoke outside the sauna room. The experience is comparable to smoke sauna, minus the smoke aroma provided by burned wood.

Inside of an electric sauna
Electric sauna is the popular choice for modern Finns.

Modern electric sauna, which is a sauna fitted with an electric stove, was originally invented in Finland in 1938, and it’s the popular choice in the modern Finnish society: it’s easy to use and can be fitted inside a city apartment with ease. Real sauna enthusiasts might claim that electric sauna misses the authenticity of a traditional sauna, but hundreds of thousands of city-dwellers with their private saunas consider access to sauna a luxury, that the modern Finn deeply appreciates.

Public and shared saunas provide access to anyone, and it’s also one of the rare places, where stereotypically quiet and introverted Finns gather to socialise and relax.

Land of a thousand lakes…and million saunas

European bath houses and related traditions date all the way back to 7000 BC. Although Finnish bathing habits are poorly documented in history, it’s believed that European bathing culture would have arrived to Finland around the same time. Earliest written mentions and descriptions of sauna customs in the historical region were written by Nestor the Chronicler in year 1112.

Age of Reformation and arrival of Lutheranism shaked Scandinavia around 1530. Although bath houses were largely destroyed in Europe during that time, and bathing became largely unpopular, the Scandinavian population continued to bathe.

Historically sauna has been a place that provided health and hygiene, shelter and relief from the cold, where children were born, and where the deceased were washed and prepared for burial. It’s not surprising that sauna has also found its way to Finnish folklore (Kalevala — Ilmarinen’s wedding) and art (Akseli Gallen-Kallela — In the Sauna). Sauna tradition is deeply rooted into the fabric of Finnish society.

In the modern day, it has been estimated that there are over two million public and private saunas in Finland, for a population of 5.3 million.

Conclusion

Using a special sensor beacon can upgrade your sauna to the next level.

RuuviTag is a highly user friendly environmental sensor that can operate in extended temperature range, such as typical sauna conditions. Its unique protective enclosure allows using the tag safely in traditional and modern saunas. Free Ruuvi Station app is fast to set up and very beginner friendly.
