Sensors
Precipitation
Doppler Radar (Pulsar Models 600 and 100)
The 24 GHz Doppler radar sensor measures the drop
speed of an individual drop of rain or snow.
Precipitation quantity and intensity are calculated
from the correlation between drop size and speed.
The sensor is fast responding with a resolution of
0.01 mm.
Tipping Bucket (Pulsar Model 601 only)
Precipitation is measured by tipping spoon and
tipping bucket processes.
Optionally, the 601 also can be equipped with a leaf
wetness sensor.

• Four ultrasonic sensors are used to continuously
collect measurements from all directions. The
resulting wind speed and direction are calculated
from the measured run-time sound differential.
• The wind sensor has no moving parts, which
makes it virtually maintenance free.

Sensors
Barometric Pressure, Temperature,
and Humidity Module
W: ColumbiaWeather.com P: 503-629-0887 E: info@ColumbiaWeather.com
• Barometric pressure is measured using a MEMS
capacitive sensor.
• Temperature measurement utilizes a precision NTC
element.
• Humidity measurement is based on a capacitive
technology. The highly accurate sensor offers
excellent long-term stability in a wide range of
environments with negligible hysteresis.

The Pulsar Weather Station model 800 includes
lightning detection by an integrated sensor which
analyzes the radio wave emission of the lightning and
delivers a count of recognized strikes.
The sensor analyzes spectrum and wave form of the
received signal to suppress the detection of man-
made electrical discharges.
Lightning Detection: Number of lightning events
Coverage Area: 5-10 km

Model 501 is rated ISO 9060:1990 Second Class. It is
intended for shortwave global solar radiation
measurements in the spectral range from 300 to 2800
nm. The thermopile detector measures irradiance up
to 2000 W/m² with response time <18 seconds and
typical sensitivity 10 µV/W/m² that varies less than 5 %
from -10 ºC to +40 ºC.
Pulsar Weather Station models 800,700 and 502 use a
silicon photodiode radiation sensor.

Calibration
25
Sensors
All sensors are calibrated at the factory.
No field calibration is required except for the altitude
on the barometric pressure sensor.
The barometric pressure sensor is sensitive to
changes in elevation of as little as 10 ft. (3 m).
Adding the local altitude for automatic pressure
adjustment is easily accomplished through the
monitoring device.

26
Operation
Once set up, the Pulsar will operate automatically by
immediately recording and sending data to the
desired monitoring device.
Reviewing data, updating sensor parameters, and
checking station operation status can all be done
either remotely or on-location through the
monitoring options.

Maintenance
While the Pulsar is a maintenance free sensor
capable of providing years of operation, there are
simple steps you can take to extend the life of the
sensor.
Periodic cleaning - To ensure the accuracy of
measurement results, the sensor transmitter should
be cleaned when it becomes contaminated.
Leaves and other such particles should be removed
from the precipitation sensor and the transmitter
should be cleaned carefully with a soft, lint-free cloth
moistened with water.
