1. Introduction
Thank you for your purchase of the Ambient Weather WS-2000 Wi-Fi OSPREY Solar Powered
Wireless Weather Station. The following user guide provides step by step instructions for installation,
operation and troubleshooting. To download the latest manual and additional troubleshooting tips,
please visit: https://help.ambientweather.net/product/ws-2000/
2. Warnings and Cautions
Warning: Any metal object may attract a lightning strike, including your weather station
mounting pole. Never install the weather station in a storm.
Warning: If you are mounting the weather station to a house or structure, consult a licensed
electrician for proper grounding. A direct lightning strike to a metal pole can damage or destroy your

Version 2.12 ©Copyright 2020, Ambient LLC. All Rights Reserved. Page 3
home.
Warning: Installing your weather station in a high location may result in injury or death.
Perform as much of the initial check out and operation on the ground and inside a building or home.
Only install the weather station on a clear, dry, day.
3. Quick Start Guide
Although the manual is comprehensive, much of the information contained may be intuitive. In
addition, the manual does not flow properly because the sections are organized by components.
The following Quick Start Guide provides the necessary steps to install and operate the weather
station, and upload to the internet, along with references to the pertinent sections.

4. Pre-Installation Checkout and Site Survey
4.1 Pre Installation Checkout
Before installing your weather station in the permanent location, we recommend operating the weather
station for one week in a temporary location with easy access. This will allow you to check out all the
functions, ensure proper operation and familiarize you with the weather station and calibration
procedures.
4.2 Site Survey
Perform a site survey before installing the weather station. Consider the following:
1. You must clean the rain gauge every few months and change the batteries every 2-3 years.
Provide easy access to the weather station.
2. Avoid radiant heat transfer from buildings and structures. In general, install the sensor array at
least 5’ from any building, structure, ground, or roof top.
3. Avoid wind and rain obstructions. The rule of thumb is to install the sensor array at least four
times the distance of the height of the tallest obstruction. For example, if the building is 20’
tall and the mounting pole is 6’ tall, install the sensor array 4 x (20 –6)’ = 56’ away.
4. Mount the sensor array in direct sunlight for accurate temperature readings.
5. Installing the weather station over sprinkler systems or other unnatural vegetation may affect
temperature and humidity readings. We suggest mounting the sensor array over natural
vegetation.
6. Wireless Range. Radio communication between receiver and transmitter in an open field can
reach a distance of up to 330 feet, providing there are no interfering obstacles such as
buildings, trees, vehicles and high voltage lines. Wireless signals will not penetrate metal

Version 2.12 ©Copyright 2020, Ambient LLC. All Rights Reserved. Page 4
buildings. Under most conditions, the maximum wireless range is 100’.
7. Radio Interference. Computers, radios, televisions and other sources can interfere with radio
communications between the sensor array and tablet. Please take this into consideration when
choosing tablet or mounting locations. Make sure your display tablet is at least five feet away
from any electronic device to avoid interference.

5.3.1 Install Wind Vane
Reference Figure 2. (a) Locate and align the flat key on the wind vane shaft to the flat key on the wind
vane and push the vane on to the shaft. (b) tighten the set screw with a precision screwdriver and make
sure the wind vane spins freely.
Note: You may need to back out the set screw first before sliding the vane onto the shaft.
Note: The wind vane shaft does not spin as freely as the wind cups. This is by design. The
dampening prevents the wind vane from spinning with the slightest breeze, which will result in
variable wind all the time. The added resistance allows the wind vane to change direction with 2 –3
mph, providing a much better wind direction tracking.

5.3.5 Install Batteries
Reference Figure 6. Insert 2 x AA non-rechargeable batteries (not included) into the battery
compartment. The LED indicator on the back of the transmitter will turn on for four seconds, and then
flash once every 16 seconds (the sensor transmission update period).
(a)
(b)
Figure 6
Note: If the LED does not light up, or stays on permanently, make sure the battery polarity is
correct, or the batteries are fresh. Do not install the batteries backwards. You can permanently damage
the thermo-hygrometer.
Note: We recommend lithium batteries for cold weather climates, but alkaline batteries are
sufficient for most climates. We do not recommend rechargeable batteries. They have lower voltages,
do not operate well at wide temperature ranges, and do not last as long, resulting in poorer reception.

Version 2.12 ©Copyright 2020, Ambient LLC. All Rights Reserved. Page 9
5.3.6 Install Mounting Pole
Reference Figure 7. The mounting assembly includes two U-Bolts and a bracket that tightens around
a 1 to 2” diameter pole (not included) using the four U-Bolt nuts.
(a)
(b)
Figure 7
Use the bubble level next to the rain sensor to make sure the sensor array is completely level. If the
sensor array is not level, the rain gauge, UV and solar radiation sensors will not measure properly.
Note: If you cannot read the bubble level due to mounting constraints, place straddle a line or
ruler level across the top of the rain gauge for easier viewing.
5.3.6.1 Aligning the Wind Direction
Locate the four-wind vane compass rose indicators of N, E, S, W (representing North, East, South and
West) at the base of the wind vane. Align the compass rose direction upon final installation with a
compass or GPS.
5.5 Best Practices for Wireless Communication
Wireless communication is susceptible to interference, distance, walls and metal barriers. We
recommend the following best practices for trouble free wireless communication.
1. Electro-Magnetic Interference (EMI). Keep the tablet several feet away from computer
monitors and TVs.
2. Radio Frequency Interference (RFI). If you have other 915 MHz devices and
communication is intermittent, try turning off these other devices for troubleshooting
purposes. You may need to relocate the transmitters or receivers to avoid intermittent
communication.
3. Line of Sight Rating. This device is rated at 300 feet line of sight (no interference, barriers or
walls) but typically you will get 100 feet maximum under most real-world installations,
which include passing through barriers or walls.
4. Metal Barriers. Radio frequency will not pass through metal barriers such as aluminum

Version 2.12 ©Copyright 2020, Ambient LLC. All Rights Reserved. Page 10
siding. If you have metal siding, align the remote and tablet through a window to get a clear
line of sight.
The following is a table of reception loss vs. the transmission medium. Each “wall” or obstruction
decreases the transmission range by the factor shown below.

5.7 Indoor/Outdoor Thermo-Hygrometer, 8 Channel (optional)
The WS-2000 supports up to 8 additional thermo-hygrometer sensors (WH31), which can be viewed
on the display tablet and Internet.
Note: Do not use rechargeable batteries. We recommend fresh alkaline batteries for outdoor
temperature ranges between -4 °F and 140 °F and fresh lithium batteries for outdoor temperature
ranges between -40 °F and 140 °F.

Version 2.12 ©Copyright 2020, Ambient LLC. All Rights Reserved. Page 12
1. Remove the battery door on the back of the transmitter(s) by sliding down the battery door, as
shown in Figure 10 .
Figure 10
2. BEFORE inserting the batteries, locate the dip switches on the inside cover of the lid of the
transmitter.

5.9 Sensor Placement
It is recommended you mount the remote sensor outside on a north facing wall, in a shaded area, at a
height at or above the receiver. If a north facing wall is not possible, choose a shaded area, under an
eve.
Direct sunlight and radiant heat sources will result in inaccurate temperature readings. Although the
sensor is weatherproof, it is best to mount in a well-protected area, such as an eve.
1. Use a screw or nail to affix the remote sensor to the wall, as shown in Figure 13.
2. Hang the remote sensor up on string, as shown in Figure 14.
Note: Make sure the sensor is mounted vertically and not lying down on a flat surface. This will
insure optimum reception. Wireless signals are impacted by distance, interference (other weather
stations, wireless phones, wireless routers, TVs and computer monitors), and transmission barriers,
such as walls. In general, wireless signals will not penetrate solid metal and earth (down a hill, for
example).

6.5.3 Weather Forecasting Description and Limitations
In general, if the rate of change of pressure increases, the weather is generally improving (sunny to
partly cloudy). If the rate of change of pressure decreases, the weather is generally degrading (cloudy,
rainy or stormy). If the rate of change is relatively steady, it will read partly cloudy.
The reason the current conditions do not match the forecast icon is because the forecast is a prediction
24-48 hours in advance. In most locations, this prediction is only 70% accurate and it is a good idea to
consult the National Weather Service for more accurate weather forecasts. In some locations, this
prediction may be less or more accurate. However, it is still an interesting educational tool for learning
why the weather changes.
The National Weather Service (and other weather services such as The Weather Channel) have many
tools at their disposal to predict weather conditions, including weather radar, weather models, and
detailed mapping of ground conditions.
