Overview
NAVLink Blue is a Bluetooth interface from Digital Yacht that brings data from wireless Ruuvi sensors onto the NMEA 2000 bus, supporting up to 16 sensors placed around the boat and broadcasting updates at 0.4Hz with 5-minute logging intervals stored for 10 days internally. The Ruuvi tags report temperature (Standard version -20C to +70C, Pro version -40C to +85C), humidity to +/-3% RH displayed as RH-%, g/m3 or dew point, and air pressure across a 500-1155 hPa range with 1 hPa accuracy shown in mmHG, millibar, inHG, hPa or Pa. Both tag versions are IPX7 rated and run on a coin cell battery lasting one to two years, communicating over Bluetooth at a typical range of 10-15 metres, while NAVLink Blue itself is self-powered from the NMEA 2000 bus.
