The HAZMAT Weather Station, P/N 102643, is a portable Weather Station designed to be quickly
deployed and operated in emergency response applications. It provides all the electronics necessary
to transmit Wind Speed, Wind Direction, Temperature, Relative Humidity and Barometric Pressure
over a spread spectrum radio system up to 20 miles. The system outputs the data required for a
CAMEO/ALOHA SAM station and is used with NOAA’s CAMEO/ALOHA (including MARPLOT)
Emergency Response software. The weather station is equipped with a flux gate compass for
automatic alignment to magnetic north. Software is included in the sensor to allow the user to enter a
declination angle to output true north, as required by the CAMEO/ALOHA software.
2.1 Specifications
Input Power: 6 - 15 Vdc; 100 mA draw @ 12 Vdc
(provided by battery/charger/solar panel from the transit case)
Operating Temp: -20° to 60°C (-4° to 140°F)
Storage Temp: -50° to 70°C (-58° to 158°F)
Humidity: 0 to 95% (non condensing)
Shock and Vibration: Withstands normal shipping and handling.
Please refer to Figures 2 and 3 for detailed installation procedures for the Spread Spectrum base
station and remote sensor.
Remote Station:
Two connectors are provided on the remote transit case. One connector (5 pin) provides power to the
sensor and receives the RS232 test data that is available inside the transit case through P/N 102607
Sensor mount on the top of the tripod. The second connector (3 pin) is for the solar panel/battery
charger provided with the system. For remote use, remove the solar panel from behind the foam in
the lid and attach it to the top of the enclosure with the Velcro strips that are on the case and the solar
panel. Plug the solar panel into the 3 pin connector to charge the battery.
Whenever AC power is available, the charger should be plugged into the system to maintain battery
life. The solar panel or AC charger will charge the battery with the power switch in either the off or on
position. The case is equipped with a battery test meter. With power switch off and solar panel/AC
charger disconnected, press the button to view the battery charge level. If the battery is below 10
volts, charge it with the AC battery charger provided in the case.
Base Station:
There are basically 3 connections to be made on the spread spectrum radio base. Please refer to
Figure 2. Always make sure the antenna is connected and the power switch is off when connecting
power to the radio. The RS232 output is connected from the base station to the PC running the
CAMEO/ALOHA software through the 9 Pin cable provided. The RS232 data rate on the radio has
been factory preset to 1200 baud, to comply with the CAMEO/ALOHA standard.
NOTE: The receiver on the radio is very sensitive to lightning. Never operate the radio without
the lightning protector installed and insure that the protector is always connected to a solid
earth ground.

P/N 102770 AIO weather sensor provided with the system samples the meteorological parameters
once per second. The microprocessor in the sensor stores these values and derives the 30-second
running averages required by the CAMEO/ALOHA software. Please refer to Figure 4 for details on
the SAM output. In addition to the SAM output, the sensor also provides an instantaneous RS232
output on the test connector in the transit case. This output can be connected to any Laptop PC or
PDA using HyperTerminal or Climatronics HAZVIEW Display Software to check proper operation of
the system. A null modem adaptor is required for the PDA, and provided in the base station radio kit.
Please refer to Figure 5 for details.
6.1 Overview
The CAMEO/ALOHA software requires Wind Direction input relative to TRUE north. The flux
compass in the AIO Weather sensor provides Wind Direction to MAGNETIC north. Software resident
in the sensor allows the setting of a declination angle to correct the Wind Direction output to TRUE
north. It is recommended that this procedure be done in the lab, but can be done in the field as well.
Once the declination angle is set in the sensor, it is stored in non-volatile memory, and does not have
to be reset each time the sensor is fielded. The declination angle must be reset only if the sensor is
used in a different geographical location separated by many miles from the location where the
declination was originally set.
It is suggested that the magnetic declination be determined before performing this calibration. Visit the
following web site for help in determining the correct declination for your site:
Enter your zip code and click "Get Location". On the next page, click "Compute!" At the bottom of the
page, Field "D" is declination in degrees and minutes. Divide minutes value by 60 to get decimal
remainder of degrees (I.E. 50 minutes = 0.8 degrees). Your sensor has been factory preset to the
declination for the zip code provided in the shipping address of your order. If the declination needs to
be adjusted, please follow the steps in Section 5.2.
6.2 Procedure
6.2.1 Equipment Required:
Desktop PC or Laptop with MS HyperTerminal software.
Serial RS232 cable, 9 pin Male to 9 pin Female (provided in the base radio kit).
6.2.2 Set up the remote and base station as noted in Figures 2 and 3. Do not turn on the power to the
remote station.
6.2.3 Start HyperTerminal on the PC or Laptop and configure it for the COM port connected to the
base station radio, 1200 baud, N, 8, 1. To find HyperTerminal click Start, Programs, Accessories,
Communications, HyperTerminal.
6.2.4 Turn on the power to the remote station and observe the screen on the PC. The declination
software tells you the current setting for the declination, and gives you 10 seconds to type CTRL-C
(hold the CTRL key down then hit the C key) Please refer to Figure 1. This is a screen capture of the
declination setting procedure. Once the procedure is completed, the Weather Station will start to
output the SAM station data. The declination calibration is complete and the station may be set up in
the field. Be sure to turn the power off in the remote station before moving the station to the field or
storing it in the transit case.

102770 AIO Compact Weather Station
Introduction & Overview – 102770 AIO Compact Weather Station
The HAZMAT RF AIO Compact Weather Station (AIO), P/N 102770, is a weather instrument that provides
measurement of temperature, relative humidity, wind speed, wind direction, and barometric pressure in a single,
compact, rugged unit.
The AIO integrates a folded-path, low-power sonic anemometer with a multi-element temperature sensor, fastresponse capacitive relative humidity sensor, state-of-the-art barometric pressure sensor and an internal flux-gate
compass for automatic alignment of wind direction to magnetic north.
The small footprint and power efficiency of the AIO make it ideal for remote regions, urban environments, air
quality networks, construction/remediation sites, and other network applications. The unit can be used in
permanent (cooperative weather networks, schools, public information dissemination) or temporary (emergency
response, audit, research program support) installations.
Designed for maximum portability and utility, the AIO is well suited for rapid deployment and use by one person
under all conditions. The unit may be mounted on a tower, tripod or vehicle mast.
Data output is a serial, digital message that can be interfaced to most data logging systems.

Because the sensor has no moving parts to wear out, periodic maintenance is not required. It is recommended
that the data be checked every 6 -12 months to be sure there has been no failure of any of the electrical
components. This can be done using Climatronics Zero Wind Test Fixture P/N 501708 and any co-located
temperature, relative humidity device such as Climatronics Fan Aspirated Psychrometer P/N C22010 and
collocated pressure sensor such as Climatronics P/N 102263 (requires laptop) or Handheld Digital Barometer P/N
M200-AI0900. In extremely corrosive environments, the condition of the connector used to mount the sensor
should be checked. The only user repairable part is the Temperature/Relative Humidity Sensor Module located
inside the removable multi-plate shield.
The Temperature/Relative Humidity Sensor Module (T/RH Module) is a single plug in module with a keyed
connector that assures correct electrical connection when the new unit is installed.
Replacement is accomplished easily with a philips head screwdriver:
Remove the two screws from the top of the shield assembly.
Slide the top shield assembly off the support posts.
Unplug the existing T/RH Module.
Plug in the new or replacement T/RH Module noting that the connector will seat easily once the key is
5. Line up the shield assembly on the two support posts and slide it back into place.
6. Replace the two screws to secure the shield assembly.
The replacement is now complete.

Appendix B
102770 AIO Theory of Operation
Climatronics’ sonic anemometer operates on the principal 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
The temperature sensor in the AIO uses a precision triple-element Thermistor. This provides highly accurate and
stable temperature readings. This allows the AIO to directly interface with the temperature sensor without
additional electronics. Sensor compensation is handled through software.
The relative humidity sensor is a capacitive element sensor. It has a linear voltage output, which allows it to be
connected directly to the AIO microprocessor. The humidity sensor elements’ construction provides excellent
resistance to wetting, dust, dirt, oils, and common environmental chemicals. A heavy contaminant layer of dirt will
slow down the sensor’s response time because it will take longer for water vapor to equilibrate in the sensor.
Pressure sensor
The barometric pressure sensor is a stable transducer using nano-technology, yielding a linear and repeatable
sensor with low hysteresis.
This 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 the
ambient temperature. The raw readings are temperature corrected by the microcontroller.
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 AIO microprocessor measures the output of the internal compass and then corrects the wind direction data
for the orientation of the sensor. The output of the AIO wind direction is relative to magnetic North.
