With reliable and constant wireless hygrometer monitoring of difficult spaces, these problems can be detected before they cause any real damage!
Purchasing hygrometers is difficult. Which brand or type is the best hygrometer? What features should I look for in a hygrometer? Should it be digital or analog?
Well, I am here to help you make the purchasing process easy by introducing you to a ready-to-use, reliable and accurate hygrometer that comes from Finland. Do you know what else comes from Finland? The happiest people of course, do you notice any correlation…?
A Digital Hygrometer is the Most Convenient Way to Monitor Humidity
The number of good, digital hygrometers is increasing all the time. With a digital hygrometer, you will get more precise information without the need to be physically present at the location you would like to monitor. We use our phones a lot. And, by receiving humidity readings directly on your smartphone, you can always make sure that the humidity levels are maintained at the correct level.
Also, humidity readings must often be obtained from difficult places. These could be attics, basements, or underneath concrete structures. In other words, in places where you are not casually hanging around a lot. With the right hygrometer, you can receive alarms if undesired humidity levels are reached, and take actions based on these alarms to prevent damages from occurring.
Hygrometer Apps are Really Important
In the digital world, apps are the key factor behind successful user experience. So, by choosing a digital hygrometer with an easy-to-use and simple application, you will get the most out of your hygrometer.
Features to look for in an app for a hygrometer:
- Up-to-date data when in range of the hygrometer/hygrometers
- Graph of the development of humidity
- Alarms if humidity is not at a desired level
- Ability to view multiple hygrometers simultaneously
Why is RuuviTag the Best Available Digital Hygrometer?
RuuviTag is a Finnish invention. It is a small environmental sensor which measures air humidity, air temperature, air pressure and movement. RuuviTag sends these measurements wirelessly to Bluetooth devices such as mobile phones.
RuuviTag sends data via BLE, Bluetooth low energy technology. This method is very energy efficient. RuuviTag measures in a refresh rate of a few seconds, but its battery normally lasts two to three years.
RuuviTags diameter is 5 centimetres (2 inches) making it a true mini hygrometer. In other words, due to its small size, you can place it almost anywhere.
In addition, RuuviTag is a very accurate hygrometer. Its humidity sensor’s typical absolute accuracy is ±2%, 20…80%, 25 °C.
RuuviTag is One the Most Durable Hygrometers
RuuviTag is durable. The basic version of RuuviTag is certified with IP67 which means that it can handle water splashes and a quick submerge in water. The basic RuuviTag’s operating temperature range is -20 °C to +70 °C (-4 °F to +160 °F). The battery inside the basic version is the factor limiting this temperature range. RuuviTag’s internal components can handle temperatures between -40 °C and +85 °C (-40 °F to +85 °F)
RuuviTag Pro is designed to be used in more challenging industrial uses. There are two versions of the RuuviTag Pro. RuuviTag Pro 2in1 and 3in1. RuuviTag Pro 2in1 is IP68 and IP69K certified and its capsule is completely waterproof. With a waterproof capsule, this sensor does not measure air humidity, thus it does not work as a hygrometer. RuuviTag Pro 3in1 on the other hand is IP67 certified. Its operating temperature is between -40 °C and +85 °C.
Ruuvi Station as a Hygrometer App
Ruuvi Station is our free mobile application. The app is super easy to use. It has the ability to alert you if humidity is not optimal. It also displays graphs for up to 10 days of history, and while in range, you will receive up-to-date information continuously.
Ruuvi Gateway Enables Remote WiFi Humidity Monitoring
RuuviTags work with Bluetooth. So, if your mobile device is too far from the sensors, their measurement will not update on the app.
To solve this problem, we have created the Ruuvi Gateway. Ruuvi Gateway has an enhanced antenna, which can hear RuuviTags in optimal conditions from up to 2 kilometres (1.2 miles) away.
Ruuvi Gateway listens to RuuviTags’ measurements and transfers them to the Ruuvi Cloud. The Gateway transfers the measurement data to the Internet so that you can review and receive humidity measurements wherever you are.
Ruuvi is a Hygrometer with Thermometer, Barometer and Movement Sensors
Even though measuring humidity is important, other factors are also important to be measured. Since we are usually interested in relative humidity, the other part of the equation is temperature. It is wise to have all of these sensors in the same device.
With multiple sensors, you can use RuuviTags to monitor other important things in your life. And by measuring everything with Ruuvi, you can collect and analyse all the data on the same application. That’s what we call convenient!
Why to use a Digital Hygrometer? – Four Examples of Hygrometer Importance
As mentioned earlier, using a hygrometer can help prevent costly damages stemming from innapropriate air humidity levels.
Humidor Hygrometer in a Cigar Box
Conditions inside cigar storing boxes should be kept at 70% relative humidity and at the temperature of 21 °C (69.8 °F).
In these conditions, cigars will be best preserved. Their aromas and structure will remain unchanged for a long time in these circumstances. If a cigar box is too humid, the cigars will turn mouldy. Conversely, if they are too dry, the cigars will crack. For more information, check out this article.
Greenhouse Humidity Monitoring Ensures Good Crops
The relative humidity inside a greenhouse should be between 40% – 70%
Keeping the relative humidity in this range will help the plants to cool down and photosynthesise. In excessive humidity, mould can start to form on plants and their perspiration can slow down. Temperature is a crucial factor in a greenhouse, so Ruuvi is a gardener’s best friend!

Indoor Humidity is an Investment for Better Health
Indoor relative humidity should be 35% and 55 %.
In colder regions, heating during winters dries up indoor air. In excessively dry air, our respiratory tract dries and we are more vulnerable to diseases. Keeping air humidity at the right level makes you feel more fresh and healthy. When the relative humidity is too high, our perspiration becomes more difficult. Our perspiration is also called sweating which is our body’s way to cool us down. This is why you feel extra hot in highly humid areas.
Wooden Instruments Require Stable Conditions
Ideal relative humidity for wooden instruments is around 40% to 60%.
Wood is vulnerable against improper humidity conditions. When the environment is too dry, wood will warp which will ruin delicate instruments. If it’s too humid, mould can start to form on the instruments.

The optimal air humidity level inside a cigar box is 70%. This level of accuracy is only obtainable with a humidor hygrometer.
Why should I buy a hygrometer?
Hygrometers help prevent problems arising from harmful air humidity levels. Mould is a major threat to your health, and to the integrity of structures. Air humidity is hard to estimate without proper equipment, so purchasing an inexpensive digital hygrometer can save you a fortune in the long run.
