Wirepas Mesh Development Kit for Measuring Temperature and Humidity with RuuviTag

Measure Like a Pro

RuuviTag Pro fits perfectly with demanding industrial and serious home uses.

RuuviTag Pro 3in1 RuuviTag Pro 3in1

Accurate and Durable Sensor for Versatile Conditions

RuuviTag Pro is a rugged IP certified environmental sensor for temperature, air humidity, air pressure and acceleration monitoring.

The Pro is based on RuuviTag’s successful concept and additionally brings several new outstanding features to the table. RuuviTag Pro is the toughest open source sensor on the market.

Mounting is finally easy and quick

We like how RuuviTags perform but we've had problems with mounting them on our machinery. The Pro version fixed this problem.

Accurate temperature monitoring is crucial to us

Our business is to measure temperatures of food and medical transportations. The NIST traceable temperature sensor is a welcomed feature.

We love the fully sealed version

We measure only temperature and we need the sensors to survive outside in pretty rough conditions. These fully sealed versions are exactly what we've waited for.


Easy setup

RuuviTag Pro tolerates wet and rough conditions.

The IP67 certified RuuviTag Pro (4in1 and 3in1) comes with a breathable membrane that enables air humidity and air pressure monitoring. It tolerates temporary wet conditions and it’s a good choice to outdoor use. The 4in1 and 3in1 models are for non-condensing uses only.

The IP68 and IP69K certified RuuviTag Pro (2in1) offers a full protection against water with its fully sealed enclosure.

Note! Please keep in mind that Bluetooth signals are strongly attenuated in the water and range will be significantly reduced. Due to very limited range it’s usually not practical to use sensor underwater. 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.

Medical Grade Temperature Accuracy

RuuviTag Pro has an extremely accurate temperature sensor on board. The sensor is designed to meet ASTM E1112 and ISO 80601 requirements for electronic patient thermometers.

Measurement resolution is  0,01 °C, while absolute accuracy is astounding at ±0,1 °C across the temperature range of –20 to +50 °C, with no calibration.

The sensor units are 100% tested on a production setup that is NIST traceable and verified with equipment that is calibrated to ISO/IEC 17025 accredited standards.

Professional Mounting

RuuviTag Pro has two strong mounting ears that allow reliable installation methods to be used. Wooden ceilings, gyproc walls, concrete foundations, you name it. Attach and measure professionally wherever you need to.

From -40 to +85 °C

RuuviTag Pro’s casing and electronics are designed to operate without interruption in a wide range of temperatures. Maintenance is minimal because the included Ruuvi CR2477T wide temperature battery lasts in normal use 1-2 years.

Frequently Asked Questions
What sensors are included in RuuviTag Pro?

RuuviTag Pro has three models:

  • Fully sealed 2in1 version that measures temperature and motion
  • Breathable 3in1 model that measures temperature, humidity and motion
  • Breathable 4in1 version that measures temperature, humidity, air pressure and motion

Please read the technical specifications for more details before ordering.

Why are there two enclosure models in RuuviTag Pro?

RuuviTag Pro’s fully sealed version is IP68 and IP69K certified. This means that it tolerates wet conditions like never seen before.

The IP67 model has a weather resistant membrane that allows air to pass through. This is a requirement to allow you to measure air humidity and air pressure.

What is included in the product package of RuuviTag Pro?
  • RuuviTag Pro
  • Quick start guide
  • Mounting screws
What are the differences between the IP67, IP68 and IP69K in RuuviTag Pro?

RuuviTag Pro has been professionally laboratory tested and certified for IP67, IP68 and IP69K.

IP67 tolerates wet condition only temporarily. It can be used outside as long as the breathing membrane will not stay wet more than 30 minutes.

IP68 certification ensures that RuuviTag Pro  will function in water depth of up to 50 meters for 24 hours.

IP69K means that the unit has undergone a challenging set of tests to ensure that it offers protection against penetration of high pressure and high temperature water of 80 °C.

What are the differences between RuuviTag and RuuviTag Pro?

RuuviTag Pro has several new features such as:

  • High accuracy temperature sensor
  • Wide operating temperature range
  • IP67, IP68 and IP69K certifications
  • Professional mounting
  • Industrial design
  • Optional expansion port
  • Sensor configuration depends on the model
