The WeatherHawk 500 series home weather station can measure and record wind speed, direction, air temperature, relative humidity, atmospheric pressure, solar radiation, and rainfall. In addition, the system can calculate and outputETValue, and then apply it to third-party systems for irrigation control.

500The series of meteorological stations are fully compatibleWeatherHawkAll versions of the designed software, data management, input power supply, and installation accessories are also compatible with all third-party software.

500A series of weather stations andWeatherHawkThe meteorological stations before the system were different in principle,500The series adopts an overall layout, with all sensors concentrated in one unit and no moving parts. Equivalent to a solid weather station with an inconspicuous external contour design, it has a very beautiful appearance compared to a sensor weather station; Meteorological stations have excellent reliability, with a long time interval between daily maintenance and necessary inspections; The structure of the meteorological station is very sturdy, which can prevent damage that may be caused by wind; And the weather station will not reduce the time required for ice removal due to blizzards or freezing conditions (note: heating sensor model,511/521Used in snowy and frozen areas

Sensor Technology

500seriesWeatherHawkThe meteorological station uses*The new meteorological measurement sensors, wind speed and direction sensors, use professional wind sensors based on ultrasonic principles, while rainfall measurement uses a solid surface, indicating that it is possible to count the falling raindrops and measure their acoustic markers. Combining these confidence, a near real-time total precipitation and precipitation rate can be provided. Atmospheric pressure, relative humidity, air temperature, and solar radiation are all scientifically calibrated sensors that can be installed on professional meteorological stations to form a measurement and monitoring system.

Wind speed and direction:

Three equivalent ultrasonic transmitters are arranged on a horizontal plane to measure wind speed and direction, Through a transmitter array, sensors measure the bidirectional transmission time along three paths, and the length of the transmission time depends on the wind speed passing through the ultrasonic path. If the wind speed is zero, then the forward and return transmission times are equal; Similarly, the upwind transmission time will increase and the downwind time will decrease, and the wind speed and direction can be calculated based on any two columns of path values. If the system wants to maintain long-term high accuracy, it is recommended to5Return the sensor to the factory for calibration once a year .

fall Rain:

By measuring precipitation through a pressure gauge tube placed at the top of the meteorological station, as a single raindrop (or hail), once it collides with the surface of the meteorological station, it will be marked by sound waves and measured once, and processed into real-time data to provide the actual rainfall amount. Based on time and rainfall, the precipitation rate will be calculated. This measurement technology eliminates all the problems caused by traditional rain buckets, such as bearing wear caused by tipping bucket rain buckets, as well as their clumsy funnels and drainage holes, and damage caused by wind.

Air temperature and relative humidity（RH）：

Air temperature and relative humidity（RH）The sensor is integrated and can be replaced by the user if needed without calibration. The relative humidity sensor is a thin polyethylene capacitor, but frequent exposure to air shortens its lifespan and makes it prone to aging. Therefore, it is recommended that users3Replace once a year to maintain the high precision of the sensor. If it is used in highly polluted air or air that often spreads chemical spray, the service life of the relative humidity sensor will be shorter. The air temperature sensor is a ceramic capacitive sensor, so it will not be affected or damaged by the environment.

Atmospheric pressure:

Atmospheric pressure is measured through a temperature corrected capacitive silicon strain gauge, which is not damaged by long-term exposure to air and does not require calibration after a period of time.

Solar radiation:

By using a silicon radiometer to measure solar radiation, a portion of the spectrum is filtered, so the sensor only measures300……1100Nano wavelength light. The performance of this sensor is measured annually in full range values2%Decrease, therefore it is recommended to recalibrate, or every3……5Replace once a year, depending on actual usage.
