2 WHIRLYBIRD WWS-A is an Automatic weather station you can count on for reliable and accurate environmental measurements. APPLICATIONS Environment monitoring Agriculture Hydrology Meteorology Stand alone weather station Marine weather FEATURE Self Contained Rugged Easy installation Plug and play sensors Low Power Consumption Easily Configurable WWS-A is a rugged self contained automatic weather station that provides general meteorological and agriculture measurements. WWS-A comes with Anemometer, Rain Gauge, Humidity & temperature sensor, soil moisture sensor and WDL-A Data logger. Other sensors like solar radiation, soil temperature, leaf wetness and pressure sensor are optional. you can buy them separately. Sensors and the data logger are mounted on a single pole of 2 inch diameter. Pole could be supported by metal cables and clamps. Station will be supplied with a 5 watt solar panel which can be mounted on pole, and the data logger will be connected to the sensors with the cables provided. WWS-A supports 4 extra analog channels for measurements. Data is uploaded over a predefined server using GPRS communication. Data can be downloaded from web servers or from data logger manually. A 4 GB SD card is enough to store lifelong data and configuration files on it. A 16x2 LCD Display provides interface for viewing sensor s instantaneous data, GPRS status and system health. It also helps in data backup and system configuration. Lithium battery is provided for long life and fast charging over a 10 watt solar panel. One extra slot is available for battery expansion.solar panel capacity can also increased as MPPT charger is inbuilt in data logger.

4 ULTRASONIC WIND SENSOR Introduction: Ultrasonic wind sensors has no moving parts that makes them extremely rugged and maintenance free. With digital serial output these sensors are easy to use and ideal for harsh locations where frequent maintenance is not possible. The two axis ultrasonic wind sensors offers fast response and update rate compared to cup type anemometers at low cost. Features: Low maintenance in absence of no moving parts, wear and tear get significantly reduced therefore low maintenance is required. Low wind speed detection could detect low wind speed which is not possible with cup type anemometers. Consistent performance over service life span. No routine calibration required. Technical Specification: Specifications Operating Conditions Operating Humidity < 5 to 100% RH Operating Temperature -35 to +70 C Storage Temperature Range -40 to +80 C Input Voltage 9 to 30 Vdc Typical Current Drain < 15 ma (@12 V) Output Signal MODBUS Outputs Parameters Wind speed and direction Wind Speed Range 0 to 60 m/s Resolution 0.1 m/s Accuracy ±0.5 m/s over full range Measurement Frequency 10 samples averaged to a 1 Hz output frequency Range Resolution Accuracy Wind Direction 0 to 359 degree 1 degree ±2 degree

7 Rain Gauge WRN-1 (Tipping Bucket Type) Introduction: The Whirlybird Model WRN-1 Tipping Bucket Rain Gauge meets the specifications of the World Meteorological Organization (WMO). Extensive use of molded thermoplastic components gives maximum performance and resistance to corrosion. Maintenance: The rain gauge should be inspected periodically accumulated dirt should be cleaned from funnel, screen and assembly. Leveling screw may be readjusted at this. Periodic calibration may be desirable to ensure measured accuracy. Technical Specification: Specifications Catchment Area Resolution Output Operating temperature 200 sqr CM 0.25 mm per tilt Magnetic Reed switch, Normally Open -20 to 50 Deg C Accuracy Up to 50 mm/ hr 2% Up to 100 mm/hr 3% Above 100 m/hr 5% Range Material used Unlimited UV stabilized ABS plastic, stainless steel

9 Air Temperature and humidity WHT-1 Introduction: The WHT-1 Both Temperature and Humidity are built into the Radiation shield at the bottom of the assembly. The integral shield limits errors due to solar radiation. The RH sensor is a capacitive element enclosed in a protective membrane. Features: Large radiation shield for better protection and air circulation. Consistent performance over service life span. Periodic calibration may be desirable to ensure measured accuracy. Technical Specification: Specifications Air Temperature Range -20 to 70 degree C Resolution 0.1 degree C Accuracy +/-0.1 degree C Sensor Type Platinum RTD / Digital Response Time 8 Second Relative Humidity Range 0 to 100% RH Resolution 0.1% Accuracy +/-2% Sensor Type Solid State / Digital Response Time Material used 8 Second UV stabilized ABS plastic, stainless steel
