Very convenient for greenhouses ⭐⭐⭐⭐

I use the RuuviTag to monitor humidity and temperature in my greenhouse. It’s the most convenient way I’ve found to remotely monitor and receive notifications to my phone.

- Mike, 47
Instant notifications! ⭐⭐⭐⭐⭐

I received an alarm from Ruuvi Station on my phone saying “humidity too low”. I was able to act quickly and prevent damage to our plants.

- Lisa, 31
Really useful ⭐⭐⭐⭐⭐

Great product. Small and easy to install. I use it to monitor conditions in my greenhouse.

How to monitor greenhouse?

With RuuviTag you can easily monitor and optimize the conditions in your greenhouse.

RuuviTag sends measurement data to your mobile device where you can view real time data and history graphs. In addition, you can set custom notifications and personalised alert messages.

Most plants thrive at temperatures between 18 °C and 24 °C. Relative humidity should be between 40% and 80%.

Easy to use with Ruuvi Station app.

Make decisions based on historical data.

Set customized alerts and receive notifications.

Most Common Questions
How does the RuuviTag work in greenhouse conditions?

The RuuviTag is perfectly suited for greenhouse climate conditions.

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 long is the Bluetooth range?

Using only Ruuvi sensors
The 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 speaker.

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 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.

Do I need to charge my Ruuvi sensors?

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.

Will RuuviTag work with my phone?

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