Ruuvi RuuviTag Bluetooth Wireless Temperature, Humidity, Air Pressure & Motion Sensor

The Ruuvi RuuviTag Bluetooth Wireless Temperature, Humidity, Air Pressure & Motion Sensor from Nomadic Supply Company is a wireless Bluetooth sensor node that measures temperature, air humidity, air pressure and movement. You can read live measurements and history data directly on your smartphone using Ruuvi’s mobile app for Android and iOS.

Ruuvi RuuviTag Bluetooth Wireless Temperature, Humidity, Air Pressure & Motion Sensor looks sleek and clean, but it can still operate in challenging environments. It’s designed with passion by the very best engineers.

Ruuvi RuuviTag Wireless Temperature, Humidity, Air Pressure & Motion Sensor FAQ’s:

Is RuuviTag water-resistant?

RuuviTag is IP67 certified (water-resistant, tested in 1 meter depth). If you are looking for a fully waterproof sensor, please check out RuuviTag Pro (2in1), which is IP68 or IP69K certified (waterproof, tested in 50 meters depth). See the certification of each sensor directly on the product pages.

Please keep in mind that Bluetooth signals are strongly attenuated in the water and range will be significantly reduced. Ruuvi sensors can then be used in narrow water if you want to maintain connection (for example pool or jacuzzi). If you want to measure deeper, you can attach the RuuviTag Pro to a string and take it back to the surface when you want to download the data history.

What are the operating conditions of the Ruuvi sensors?

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.

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.

What is the 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.

Ruuvi RuuviTag Works with the Victron Cerbo GX:

The Ruuvi RuuviTag Bluetooth Wireless Temperature, Humidity, Air Pressure & Motion Sensor allows you to integrate these 4 data types into a Victron Energy Cerbo GX Communication Center (BPP900450100). Unfortunately, the Bluetooth connectivity on the Victron Energy Cerbo GX is too weak to support the Ruuvitag so Victron recommends using one of the below third-party USB to Bluetooth adapters:

• Logilink BT0037
• TP-Link UB400(UN)
• Ewent EW1085R4
• Laird BT820
• Laird BT851
