The microcontroller polls the pressure sensor module once per second for the barometric pressure and ambient temperature. The raw readings are temperature corrected by the microcontroller. Wind Measurement A unique folded-path, low-power sonic anemometer operates on the principle that the speed of the wind affects the time it takes for sound to travel from one point to a second point. If the sound is traveling in the direction of the wind, then the transit time is decreased. If the sound is traveling in a direction opposite the wind, then the transit time is increased. Fluxgate Compass The internal compass module is low power and compact. It employs a pair of magneto-inductive sensors which change inductance with varying magnetic field strengths, to sense the Earth s magnetic field. The microprocessor measures the output of the internal compass and then corrects wind direction data for the orientation of the sensor. The output of the wind direction is relative to magnetic North. A user programmable value of Magnetic Declination may be entered through terminal mode to enable output relative to True North rather than Magnetic North. Optional Tipping Bucket Rain Gauge Complex spun collector funnel with a knife edge that diverts the water to a tipping bucket mechanism. For each tip, a magnet causes an electronic pulse that is recorded. The rainfall sensor is completely automatic - spent water drains out of the bottom of the housing, requiring no servicing.

Relative Humidity Measured with a capacitive polymer sensor, this construction provides resistance to wetting, dust, dirt, oils, and common environmental chemicals. Barometric Pressure Stable transducer using nano-technology yields a linear and repeatable sensor with low hysteresis. The piezoresistive pressure sensor module is mounted on a small electronic circuit board. A microcontroller controls the operation of the sensor and the data interface. The microcontroller polls the pressure sensor module once per second for the barometric pressure and ambient temperature. The raw readings are temperature corrected by the microcontroller. Wind Measurement A unique folded-path, low-power sonic anemometer operates on the principle that the speed of the wind affects the time it takes for sound to travel from one point to a second point. If the sound is traveling in the direction of the wind, then the transit time is decreased. If the sound is traveling in a direction opposite the wind, then the transit time is increased. Fluxgate Compass Low power and compact, the internal compass module employs a pair of magneto-inductive sensors, which change inductance with varying magnetic field strengths, to sense the Earth s magnetic field. The microprocessor measures the output of the compass and corrects wind direction data for the sensor orientation. The output is relative to magnetic North. A user programmable value of Magnetic Declination may be entered to enable output relative to True North rather than Magnetic North. Optional Tipping Bucket Rain Gauge Complex spun collector funnel with a knife edge that diverts the water to a tipping bucket mechanism. For each tip, a magnet causes an electronic pulse that is recorded. The rainfall sensor is completely automatic - spent water drains out of the bottom of the housing, requiring no servicing.

49 Weather MicroServer Required with the Pulsar Weather Station, the Weather MicroServer converts the sensor data into a format that can be monitored through the MicroServer s user interface, the Weather Display Console and/or Weather Master Software. The Weather MicroServer 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. 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. MicroServer Optional Sensors: Additional sensors can be added to a Pulsar Weather Station by connecting directly to the MicroServer. This allows for an even wider variety of parameter measurements. These include visibility, solar radiation, photosynthetically active radiation (PAR), and temperature (panel, soil, water or ambient). Visibility Sensor 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.

The resulting wind speed and direction are calculated from the measured run-time sound differential. Air Temperature and Humidity Temperature is measured by way of a highly accurate NTC-resistor while humidity is measured using a capacitive humidity sensor. To help mitigate the effects of external influences (e.g. solar radiation), these sensors are situated in a fan-aspirated housing. Air Pressure Absolute air pressure is measured with a built-in micro-electro-mechanical sensor (MEMS). The relative air pressure referenced to sea level is calculated using the barometric formula configured with local altitude input by the user. Precipitation The Model 600 precipitation sensor works with a 24GHz Doppler radar, which measures drop speed and calculates precipitation quantity and type by correlating drop size and speed. Model 601 utilitizes a tipping-bucket rain gauge. An optional leaf wetness sensor can be added to the 601. Solar Radiation The thermopile sensor construction measures the solar energy that is received from the total solar spectrum and the whole hemisphere (180 degrees field of view). Compass The integrated electronic compass can be used to orient the sensor housing and automatically correlate wind direction.
