The sensor provides chart plotters and instrumental displays with humidity and air temperature measurements and calculated dew point temperature. The device is plug and play; you only need to plug it into a NMEA 2000 backbone to get readings on all chart plotters and instruments on board.
This product can be used for weather monitoring and fog prediction; mold prevention by monitoring of water intake or moisture condensation in lockers; and remote monitoring of living quarters. From the helm you can see how comfortable it is in the cabin.
The Device is equipped with a high quality sensor that provides ±2 % RH and ±0.3 °C accuracy in most of the operating range. Operating range is 0-100 % RH and -40..120 °C( -40..248 °F ).
The Humidity Sensor sensors support firmware updates and three programming (configuration) methods. The simplest way is to use a special installation description string which can be entered for the device in some modern models of chart plotters or in special software. The Device can be configured to display inside (saloon, cabin) or outside air temperature and humidity. Configuration of the data instance is also supported. For example, “Inside Humidity” with data instance 0, 1, 2 can indicate humidity in the saloon, and the bow and aft cabins. Chart plotters with factory settings are usually able to show only one value with data instance 0, but manufacturers may supply dealers and professional installers with internal instruments to customize chart plotter screens. That allows installation of dozens of humidity sensors in a single network.
The Humidity Sensor can be configured by user to turn on or off specified channels of digital switching equipment. It operates by air temperature, relative humidity and by the difference between air temperature and dew point temperature
