Ensure that your instrument stays in tune

Acoustic instruments, especially the more expensive ones, are most affected by humidity and temperature because they’re made from ultra-thin sheets of wood and held together primarily by glue.

For example, the wood in a guitar can swell tremendously, causing glue joints to fail, finish to lift, and neck angles to go bad. Distortions in the wood can remain even after other damage has been repaired, leaving the guitar cosmetically disfigured.

To best protect your instrument, look for steady and moderate temperatures. Musical instruments of all types do well in temperatures of about 21 degrees Celsius or 70 degrees Fahrenheit.

Most experts and instrument manufacturers agree that an ideal relative humidity range of 40-50 % is best for storing instruments. Anything less could cause wood to shrink, lowering the top and strings, which causes even more stress and eventually cracking.

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.

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.

No, the power of the Ruuvi sensors is supplied by CR2477 coin batteries, included in the box. One battery lasts usually between 2 to 3 years in continuous use. The battery is easily replaceable by the user making our products very sustainable and lowering their maintenance costs to a few euros every two years.

The Ruuvi Station app can be downloaded both from the Play Store (Android) and the App Store (iOS). It is also available for tablets.
