The RuuviTag 4in1 is a wireless, open-source sensor that measures temperature, air humidity, air pressure, and movement. Measurement results are sent directly to your phone within a Bluetooth range of up to 100 meters. Review live and historical data directly on your smartphone or tablet using the Ruuvi Station app. Set up takes a few minutes and the standard watch battery (included) lasts 12-24 months and is easy to replace. Ruuvi Bluetooth sensors also communicate with Victron Energy GX devices. Once connected to a Cerbo GX, Ekrano GX or GlobalLink 520, Ruuvi sensors report environmental data to Victron's free remote monitoring platform, VRM. This also allows users to, for example, use Relay 2 on the Cerbo GX to turn on the fan in your camper van when the temperature gets above 76 degrees. One less thing to worry about and one more valuable piece of information in your pocket. Place these sensors anywhere (humidor box, guest cabin, freezer, boat hull, salt water fish tank....go nuts) and set up email alerts in VRM to let you know if something is too wet, hot, or cold.
