1.1 What's New with the WS-1002-WiFi Sensor Array

The WS-1001-WiFi uses rechargeable batteries for energy storage. The WS-1002-WiFi improves on
this design by charging a super capacitor instead of rechargeable batteries. The non-rechargeable
batteries provide back-up energy.
With the WS-1001-WiFi, the rechargeable batteries have a limited temperature range and prone to
leaking. This problem is resolved with the WS-1002-WiFI by using high quality non-rechargeable
batteries, like Lithium e2 Energizer batteries.

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: 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. Pre-Installation Checkout and Site Survey

3.1 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 of
the functions, insure proper operation, and familiarize you with the weather station and calibration
procedures. This will also allow you to test the wireless range of the weather station.

3.2 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 4 x (20 – 6)' = 56' away.
4. Wireless Range. The 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, high voltage lines. Wireless signals will not penetrate metal
buildings. Under most conditions, the maximum wireless range is 100'.
5. Radio interference such as PCs, radios or TV sets can, in the worst case, entirely cut off radio
communication. Please take this into consideration when choosing console or mounting
locations. Make sure your display console is at least five feet away from any electronic device
to avoid interference.
