What Are The Differences Between RuuviTag Models?

Currently there are three different models of RuuviTag. Each model has been designed to fulfill a slightly different purpose but they all are accurate wireless thermometers. In this article, we’re going to go through the main differences between RuuviTag models, so that you can choose the best model for your use purpose.

In general, there is the basic RuuviTag and two RuuviTag Pro models. The basic model is the first product from Ruuvi. It measures air temperature, air humidity, air pressure and movement of the sensor. You can easily recognize the original RuuviTag from the other models from the color of the sensor; RuuviTag is white while RuuviTag Pros are black.

RuuviTag Pro is a newer model of RuuviTag designed to be used in more challenging and tough environments and especially for businesses. RuuviTag Pros have a more accurate temperature sensor and it has mounting screw holes in its enclosure. There are two different models of RuuviTag Pro: RuuviTag Pro 3in1 and RuuviTag Pro 2in1.

RuuviTag Pro 3in1 has a breathing membrane hole on its enclosure making it capable of measuring air temperature, air humidity and movement of the sensor.

RuuviTag Pro 2in1 is a fully sealed version and it’s tested for waterproof. This means that it can be submerged underwater but it isn’t capable of measuring air humidity or air pressure. Thus, it measures two variables: air temperature and movement of the sensor.

How to choose the best model for you?

Choosing the best model for you depends on the place you intend to use the RuuviTag. If you want to measure water temperature or temperature in general in a place that is really humid, you should choose RuuviTag Pro 2in1. Keep in mind that water obstructs Bluetooth signals heavily and you are not able to measure deep water temperature continuously.

If you want to measure air pressure, then you should opt for RuuviTag 4in1. It’s the only sensor with a barometric pressure sensor. In general, RuuviTag is a viable option for most use cases.

If you think that the sensor may take some hits and the environment you want to use it in is hot or cold, then you should choose RuuviTag Pro 3in1. This model works well for businesses as it is easy to attach and it is slightly more accurate than RuuviTag 4in1.

What are the differences between IP67, IP68 and IP69K ratings?

IP67 tolerates wet conditions only temporarily. It can be used outside as long as the breathing membrane will not stay wet for more than 30 minutes. Also, if you use these devices in an environment where relative air humidity is close to 100% for longer periods, there is a risk of water condensing inside the RuuviTag. This can possibly impose problems to the device.

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.
