RuuviTag Pro 4-in-1

Temperature: °C, °F, K; typical accuracy ±0,1 °C @ 5-60 °C (±0.36 °F @ 41-140 °F).
Air humidity: RH-%, g/m3, dew point; typical accuracy ±2 RH-% @ 20…80 %. Range: 0-95 %.
Air pressure: Pa, hPa, mmHg, inHg; typical accuracy ±1 hPa. Range: 500-1155 hPa.
Motion: Movement counter. Counter is incremented when acceleration exceeds the threshold on any axis.

Industrial Wireless Temperature and Humidity Sensor

RuuviTag Pro is an environmental sensor that fits perfectly with demanding industrial and serious home uses. You can read live measurements and history data directly on your smartphone using Ruuvi’s mobile app for Android and iOS, or pair it with your Bluetooth capable Victron GX device such as the Cerbo GX to monitor and even control relays (Bluetooth USB adapter recommended and requires Venus OS v2.80).

Wet-Certified

RuuviTag Pro tolerates wet and rough conditions. The IP67 version tolerates wet conditions only temporarily. It can be used outside as long as the breathing membrane that measures humidity will not stay wet for more than 30 minutes.

The IP67 certified RuuviTag Pro (4-in-1) comes with a breathable membrane that enables air humidity monitoring. It tolerates temporary wet conditions.

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, gyprock 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 up to 2 years.

Controlling a relay on temperature

The relays on the GX device can now be controlled by temperature.
For example to switch a fan or heating pad. Here are two screenshots showing the configuration:

In the above example, the second relay will switch when the temperature in the engine bay rises above 45 degrees, starting the fan and it will switch the fan off once the temperature drops below 40 degrees C.
