Solid-state Bluetooth Compass
Although I really think that the ZigBee wireless communications standard is better suited than Bluetooth for use in a marine electronics context, more and more Bluetooth enabled equipment is coming to the market. Elproma’s solid state electronic compass is a good example of that.
“The new ECS1 from Elproma is a solid-state electronic compass sensor with an accuracy of 1 degree, and is available in several different configurations. The interface is available in three formats: NMEA 0183, NMEA 2000 or Wireless Bluetooth. Two new indicators have also been released – the ECI1 and the ECI2. The ECI1 is an LCD indicator with a moving bended-course scale, while the ECI2 features a 7-segment display for those wanting a larger view of the compass reading. Both indicators are also available in NMEA 0183, NMEA2000 and wireless Bluetooth interfaces.”
