Ambient WS 2902C. The Rain Gauge

Two Year Update For The Ambient Weather WS-2902 Review

The Ambient Weather WS-2902 review starts with some history of owning the weather station now for two years, becoming familiar with the features and benefits of owning it.

I was looking at home weather stations that were WiFi-connected without wires and not a complicated install. My considerations include the Davis equipment I owned that weather station several years ago. Additionally, it was a little out of my price range.

My particular setup will have the sensor unit mounted over 100 ft from the display, which was a concern. Being the WS-2902 communicates via RF (915 MHz) from the console to sensors, I would not have a clear line of sight, and signals would pass through multiple walls to the outside sensors.

It would be stretching the Ambient Weather WS-2902 capabilities. Still, I decided to give it a shot and purchased the home weather station in 2019.

The Ambient Weather WS-2902 checked all the boxes for what I was looking for, and it did not disappoint. The bottom line, the weather station did not disappoint. Currently, in June of 2021, there are over 6000+ reviews with 4.5 stars.

Lots Of Exciting Features For Most Weather Stations

The Ambient Weather WS-2902 includes monitoring features for the most discerning weather watcher. The LCD has a bright backlit screen viewable from most locations. It does fade when viewed from the side, but very doable for personal weather stations. Here’s a list of monitoring weather sensors;

  • Wind Speed Cups
  • Wind Direction
  • Rainfall/Rain Gauge Funnel Type
  • UV
  • Solar Radiation Sensor
  • Barometric Pressure Sensor
  • Indoor and Outdoor Temperature (F and C)
  • indoor/outdoor humidity
  • Display Console
  • Connectability to Smart Devices

The weather station also calculates dew points, wind chill, and heat index. So as you can see you get more than just the wind speed.

There are additional sensors that are available to the updated WS-2902 display. I have not added any to mine yet.

Monitor Weather Conditions via Weather Underground

My configuration allows me to connect to the or Weather Underground network, which will retain my data for yearly, monthly, and daily totals; in addition, I can easily refer back to weather report data.

The weather station installed on my ranch is accessible from anywhere with Internet connectivity. Using their website or app. I can also compare my rain totals or temperature ranges with neighbors. Using the WS-2090 and Ambient Weather’s cloud storage, one could store a wealth of weather data.


The sensor suite is an all-in-one sensors suite and the majority come pre-assembled. Even though there are mechanical difficulties there should be no problems when you put it together.

The station is accompanied by one of the most understandable weather station manuals I had seen. We typically recommend using the ambient weather EZ30-12 stable assembly kit to get the most accurate measurements from your sensor.

My Install Setup

FIgure 1

I am a Ham Radio operator and had some top section on Rohn 25g tower section available and used that to mount the sensors. Using High Quality 5′ Long Mast Pipe, it’s secured with bolts to the top of the tower section.

There are several options one could use to mount The Osprey Sensor Array. Chimney or any method to install to get a little past the roofline for wind speed accuracy. The LCD Display is in my Ham Shack which is about 150 feet from the outside unit.

As you can see in Figure 1, my unit is in the air about 30 feet; in addition, this gives me a clear zone, free of any obstacles. The one downside is that it can get breezy, affecting the accuracy of the funnel gauge. Check out my previous post on the best place to locate the most accurate readings

The Good

The ease of install is a definite plus for the Ambient Weather WS-2902 WiFi smart weather station.

RF(915) makes installing much easier than the wired units, but there are some disadvantages which I will discuss in the next section.

Stream weather data directly to the internet to view anywhere with their Ambient Weather App. Handy when comparing month over month and yearly totals.

Integration with smart home technology using Google Assistant or Amazon “Alexa” for checking current conditions with the “Hey Alexa, ask Ambient current weather conditions.”

Also, the battery on the sensor array is solar power. I have not changed the battery in two years.

A Couple Of Things You Should Know…

Ambient Weather has released a few different models of the WS-2902.

This is not to be confused with the Ambient Weather WS 2902A weather station that was also released. This weather station is no longer available for sale. The Ambient Weather WS-2902C is a second upgrade to the popular WS-2902A. The new version, the WS-2902C, supports 8 thermo-hygrometers and 2 air quality sensors (1 indoor and 1 outdoor). The new LCD on the WS-2902C is much improved. The weather station LCD screen for displaying data, weather forecast, etc.

The WS-2902c weather station is the current version of the Ambient Weather WS-2902 weather station that is available for purchase.

Not So Good

My number one negative would be the dropped data from both the Osprey to display. I can’t blame the overall unit because I am stretching the recommended site distance.

It’s not too critical for my application, but I would recommend keeping the sensors of the weather station within specs if you need uninterrupted data.

Make sure the funnel for the rain gauge is free of spider webs or wasp nests. The moisture in the gauge tends to attract critters; consequently, I’ve had to clean it out. This has occurred twice in two years.

The accuracy of the rain gauge is fair but not precise moreover, many conditions will sometimes affect the data you will collect. If installed in a fairly windy location, it will affect rainfall totals.

In many installs, you will have a trade-off between distances and being far from obstacles. In other words, set realistic expectations for the unit.

Is there any better Alternative Weather Station?

The WS-2902 list of features throws all other good weather stations at that price range out of the water. If you’re looking for accurate readings I’d recommend the more expensive Ambient Weather WS-5000.

It features an ultrasonic anemometer to deliver faster and more accurate wind readings and a wireless rain gauge with a larger funnel, ensuring rainfall accuracy. See all available Ambient weather stations.

Final Thoughts

I’m a weather geek and fascinated with the subject. I wanted a robust weather station the Ambient Weather WS-2902  checked all the boxes.

All the sensors for weather data collection and connectivity with the internet make this a terrific unit for your home.

After two years of real-world application, I’m pleased with its performance and durability!
