Product Overview

As weather patterns continue to shift and change, understanding how they are changing becomes increasingly important. With weather stations like the Ambient Weather WS-1002 spreading, sharing data and increasing that communal knowledge becomes easier and easier. The Observer Wireless weather station for home comes with an all-in-one sensor array with an 8-inch Pole.

You can use alternate Mounting Solutions including mounting the sensor array to any one or two inch diameter pool. The sensor array is capable of fencing the following data with the noted accuracy.

Ambient Weather WS-1002 Observer Weather Station

Ambient Weather WS-1001

  • Wireless sensors and WiFi connectivity
  • Outdoor humidity accuracy: ± 5 percent
  • The WiFi Color Display Console
  • 7.28 pounds weight
  • Outdoor temperature sensor with a range of -40 to 140 degrees Fahrenheit with an accuracy of plus or minus 2 degrees Fahrenheit
  • Outdoor humidity range from 10 to 99% with an accuracy of plus or minus 5%.
  • Barometric pressure from 8.85 to 32.5 inHg
  • Wind speed and direction with samples taken once per second.

The weather station is wireless and updates to the base station once every 16 seconds. The outdoor sensor does require three AA batteries as a backup to the solar panel. The sensor array communicates with the tablet base station via line of sight RF at 915 megahertz. The display console then connects to the internet via Wi-Fi.

This weather station comes with a sensor that is meant to be mounted indoors. This sensor transmits indoor temperature humidity and barometric pressure to the sensor array which then communicates that information to the display console. The indoor remote sensor requires two AAA batteries.

One key benefit to this weather station is that it is able to connect to the ambient Weather Network. This connection sends real-time data to ambient weather the cloud service provided by the manufacturer. With this data in the cloud, you can then review indoor and outdoor conditions on any smart device or your computer. You can also download the information to perform more detailed analysis. You can also connect to Wunderground, a data site that analyzes and Compares data from personal weather stations around the world. With this access you can compare and analyze real-time data from nearly 40,000 weather stations. Wunderground also connects to the Weather Underground app and WunderMap.

This sensor is compatible with Google home assistant, Alexa, and IFTTT. You can also set email or text alerts for multiple parameters which also are recorded in a personal timeline for your review.

How is the UV Index Calculated and What Does it Mean?

The UV index is an indicator of how strong ultraviolet radiation from the Sun is at ground level. In order to calculate the UV index, measurements are made of the ozone around the entire Globe. This is important because ozone is able to absorb ultraviolet radiation. It is more capable of absorbing short wavelength UV than longer wavelengths. When talking about the UV index, and there is the total UV index which measures wavelengths between 280 and 400 nanometers, UVA index which is 315 to 400 nanometers, and UVB which is 280 to 340 nanometers.

Once the strength of these UV rays is calculated, next the sensitivity of human skin to UV radiation is taking into consideration. After that, adjustments must be made for cloud cover and elevation. The intensity of ultraviolet radiation increases 6% per kilometer above sea level. Likewise, cloud cover absorbs ultraviolet radiation which will lower the UV index. For example overcast Skies only allowed 31% of total UV radiation through while scattered clouds allow 89%.

Once that happens, the effective strength of the ultraviolet radiation is calculated, and the UV index is determined. The ultraviolet index scale is important because it tells you how much time you can be exposed before you're in danger of harmful exposure.

At 02, you are at low risk and can stay outside without worried and with minimal sun protection. At a UV index of 3 to 7, you should be wearing at least SPF 15 sunscreen with protective clothing. You should also seek shave during the late morning through mid-afternoon when exposure Peaks. Add 8 and above on the UV index, you need to be especially careful. Apply broad spectrum sunscreen and seek shade or protective clothing during Peak exposure hours. If you are curious about when peak exposure is, one way is to use the shadow rule. When your Shadow is taller than you are, your UV exposure is lower. When your Shadow is shorter than you are, you are being exposed to higher levels of ultraviolet radiation.


This weather station is a great economical option if you are looking to get more information about the weather in your local area. With the ability to send data from the sensor array wirelessly to the control tablet, and the tablet's ability to connect via Wi-Fi to various Weather Services, you have a lot of information at your fingertips. With the tablet storing data for years and including a slot for an SD card, storing and analyzing weather data has never been easier.
