The Orion Weather Station™ includes a high-tech, all-in-one sensor module with ultrasonic wind direction and speed measurements, a highly-accurate impact rain sensor, capacitive relative humidity, temperature and barometric pressure readings.  High accuracy and fine resolution make this system ideal for precision weather  monitoring. Available in three types of systems – fixed-mount, vehicle-mount, and the Orion  Nomad™ portable weather station – Orion data can be monitored with our proprietary Weather Display Console and/or WeatherMaster™ Software. Orion LX™ weather stations include the Weather MicroServer for Internet-ready output as well as industrial automation interfaces including Modbus/TCP.

Color Weather Display Console™
The Weather Display Console uses “intelligent” touch-screen technology. With its programmable microprocessor and abundant memory, the console displays weather information, performs complex computations, and stores data. The Weather Display Console features a seven-inch, TFT color LCD panel with 800 x 480 pixels resolution. It can connect directly to the weather station with a serial port or to the Weather MicroServer utilizing existing Ethernet. The display console is flexible and can be factory-programmed to suit specific market and industry requirements. It is available in three mounting options: • Desktop/Wall-Mount • Panel Mount/Flush Mount • 19'' Rack Mount.

WeatherMaster™ Software
This professional-grade software is designed to optimize the capabilities of Orion Weather Stations. Providing real-time computer weather monitoring, WeatherMaster offers:

Display and automatic logging of all measured and calculated parameters
Downwind vector wind and wind character-plotting screens
An open Microsoft Access® database for archival with easy retrieval and compatibility with other Windows® programs
On-the-fly graphing and trend display of all parameters
Alarm notification via computer, email, pager or cell phone
Multi-station monitoring and data acquisition
Quick-North orientation
Interface with CAMEO/ALOHA software for plume modeling and evacuation corridor predictions
Weather MicroServer™
The Weather MicroServer is a self-contained, proprietary computer utilizing an embedded Linux operating system. It creates an “Internet-ready” weather monitoring system by automatically providing FTP output, XML web service, and Internet browser user interface. SNMP and Modbus/OPC communication protocols are standard for Industrial Management applications. The Weather MicroServer has datalogging capability. It connects to your network with an included Ethernet cable. Two serial ports offer interface to both the Weather Display Console and additional peripheral devices or sensors such as visibility, solar radiation, and the Orion LT wind sensor.  The Weather MicroServer can provide real-time weather data to WeatherMaster Software over the network. This allows users to simultaneously monitor the weather using WeatherMaster on any network computer.

Parameter Measurements
Barometric Pressure, Temperature, and Humidity are combined in a tri-sensor module utilizing a capacitive measurement method for each parameter.A radiation shield protects the sensors from both scattered and direct sunlight and precipitation. The composite material in the plates offers excellent thermal characteristics and UV stabilized construction. The white outer surface reflects radiation, while the black inside absorbs accumulated heat. The internal sensor module is easily replaceable and available as a spare part. Barometric pressure is measured using a silicon-based sensor. The temperature sensor is ceramic. Relative humidity measurement is highly accurate with negligible hysteresis and excellent long-term stability in a wide range of environments.
Wind Measurement Wind speed and direction are measured using advanced ultra-sonic technology. Three equally-spaced ultrasonic transducers on a horizontal plane ensure accurate wind measurement from all directions, without blind angles or corrupted readings.
Rainfall Measurement Rainfall is measured with an impact sensor which detects the size and impact of individual rain drops. The resulting signals are proportional to the volume of the drops. Hence, the signal from each drop can be converted directly to the ccumulated rainfall. This measurement method eliminates scattering, flooding and clogging, as well as wetting and evaporation losses.
Additional Calculated Parameters Data from these sensors are computed to provide calculated parameters including Dew Point, Heat Index, Wind Chill, Degree-Day Temperatures and Density Altitude.
