1. Ruuvi RuuviTag Bluetooth Environment Sensor 4 in 1

RuuviTag Bluetooth Sensor Temperature, Humidity, Air Pressure and Motion Sensor

The RuuviTag is a wireless Bluetooth sensor that measures temperature, humidity,
air pressure and motion.
With the Ruuvi mobile app for Android and iOS, you can read live measurements and history data directly on your smartphone.

Furthermore, you can integrate the RuuviTag sensors into your system via the Victron Energy GX devices* such as Cerbo GX or MultiPlus GX* and thus view the data anywhere via the VRM Monitoring Portal. Now also on your mobile phone via the VRM widget.

With the Cerbo GX you can also control relays depending on the temperature.

Ruuvi sensors and app are open source, so there are hardly any limits to your ideas.

Let your imagination run wild and measure almost anything at home, at work or during your hobbies.

- Temperature units (Ruuvi-Station App) - Celsius, Fahrenheit, Kelvin
- Humidity units (Ruuvi-Station app) - relative humidity, absolute humidity, dew point
- Pressure units (Ruuvi station app) - Pa, hPa, mmHg, inHg
- Temperature sensor accuracy - Typical absolute accuracy ±0.2 °C at 5...60 °C, output resolution 0.01 °C
- Humidity sensor accuracy - Typical absolute accuracy ±2 %, 20...80 %, 25 °C
- Accuracy of pressure sensor - Typical absolute accuracy ±1 hPa

- Certifications - CE, FCC, ISED, TELEC, IFETEL, NOM, RTCA DO-160, RoHS, IP67

* NOTE: The Cerbo GX's Bluetooth is not reliable enough to work with Ruuvi sensors. Therefore, if you are installing Ruuvi sensors, you will need to install a Bluetooth USB adapter. Information and adapters can be found here. The following USB Bluetooth adapters work, but we do not sell them.

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

All tested from -17 to 70C.

Ruuvi Station App
Ruuvi Station collects temperature, relative humidity, barometric pressure, signal strength (RSSI) and motion data from all nearby RuuviTag devices and displays this data in real time. With Ruuvi Station you can manage your RuuviTag devices, change background photos and visualise the collected weather data.
