Description

The WH31L lightning detector is an add-on sensor that connects to your Ambient Weather weather station. The sensor detects lightning strikes and transmits this information once every 79 seconds to the display console and Ambient Weather Network. The sensor has three settings to adjust the sensitivity for possible interference. Mounting the WH31L out in the open can lead to better readings and less interference, but the IPX rating is not sufficient for sustained direct rain contact. If mounting outside, it is highly recommended for this device to be mounted in an enclosure, such as the Ambient Weather WH31-SRS Solar Radiation Shield to protect it from the elements This sensor is not intended for stand alone use, but integrates with most of our weather stations. Includes Radio Controlled Clock (RCC) receiver, and is also compatible with NIST date and time synchronization over the Internet. ● WS-1551-IP ● WS-1938 ● WS-1965 ● WS-2000 ● WS-5000, WS-5000-IP, WS-5050 ● ObserverIP, ObserverIP2.0, WeatherHub ● Console Firmware Version 1.6.2 or greater ● Wi-Fi Firmware Version 4.2.2 or greater Forge connections within the weather enthusiast community by seamlessly linking your Ambient Weather station to the Ambient Weather Network (AWN).

Love it. I ordered the lighting sensor and the solar radiation shield as a kit since the lighting sensor needs to be protected outside. I easily attached the housing to the nub on top of my WS-2000 sensor array and it's about 25 feet off the ground. As soon as I put batteries in the sensor, it made a connection to my console. I shows up as a lighting bolt in the upper right corner of my WS-2000 console. The lighting bolt icon will flash if it has a active lighting detection. The lighting bolt icon is steady on with no detection. It also shows data such as distance, days since last lightning detection, and the count of lightning detected for that event. (I provided a picture of the display to show the display). Note, that this sensor shows distance, but not direction; however, I'm ok with that since I can check the local radar to see where the storms are. Mine has been detecting lighting up to 25 miles. I compared the lighting strike distance of this sensor against the lighting strike map on AccuWeather and the distance was right on. Finally, I set up an alert in the Ambient Weather app to notify me via the app as a notification. If lighting is striking 20 miles or less away from my home ever 10 minutes I get a banner on my android phone. (Screenshot provided of alerts in the app). This app alerting is a free feature in the Ambient Weather app and is extremely easy to configure distance in alert times. It you want to receive SMS alerts, that is a premium feature you need to pay for..... but way if the app alerts are free? ... show more

    • Excellent detection range if you give it a clear line of sight
I added the WH31L to my Ambient Weather WS-2000 weather station. If you read the documentation it suggests not placing it inside of a building because it will attenuate the detection range. (As an RF engineer I totally get-it, their statement is accurate). What I did was to double sided sticky-tape it to the center of a window pane in one of my upstairs bedrooms where the window faces west. I set the sensitivity to the maximum because there are no electronics nearby.. By the way, do not set it to maximum if you have something like a laptop or computer within five or six feet of it. That will make the detector go crazy from all of the RF interference and the little fogged out area on the detector will just turn solid red as if it was detecting one constant lightning strike. Today we had our first thunderstorm and I used the Ambient Weather app on my phone with alerts set for lighting detection turned on (It SMS messages me). As soon as I got the first notification I checked the Ambient Weather app and it detected lighting at 24 km (roughly 19 miles). I compared that to the Lightning detection network (you can use Weather Underground to see something really close to that) and the strikes were about that distance away. In the hour long thunderstorm I detected more than 422 lighting strikes. Some were very close (less than a km) most were further away. I did not see many beyond 24 km so that gives you an idea of what detection is like from a second story window with no metallic objects nearby. I am very pleased with the detector. It integrated easily and only required two Lithium AA batteries (not included with this sensor, some other Ambient Weather sensors come with batteries, this one does not). ... show more

    • Works as advertised. Good option/alternative to the Ecowitt WH57
I own the Ecowitt HP2560 base station and WS90 weather station. I tried the Ecowitt WH57 lightning detector and experienced the dreaded false positive strikes that didn't stop regardless of dip-switch settings. I just figured my urban setting just had too much EM interference. However, I learned that this Ambient Weather lightning detector would be recognized by the Ecowitt base station work seamlessly, so I decided why not and purchased it. It's more expensive than the Ecowitt and doesn't come with the radiation shield, but the shield can be purchased separately. After installing this into the radiation shield that came with faulty Ecowitt WH57 I sat patiently waiting for false strikes. They didn't come. About two hours later, a thunderstorm passed about 15 miles north. It registered the strikes from 14 miles away. I'm currently getting a storm and it's registering every strike. No false strikes at all! This thing is a keeper! Maybe it's just a crap-shoot on these units, I don't know. But perhaps the QA on the Ambient Weather version is a little better perhaps. They are made by the same manufacturer as the Ecowitt cousins, but for whatever reason the Ambient Weather version has better ratings and less reports of false strikes. So, if you have an Ecowitt station and are hesitant of the Ecowitt lightning detector due to the ratings, give this one a shot. ... show more

    • Works, but there is no way to fine tune distance
Review Image by EricB
It detects lightning strikes, but the distance is 7-10 miles off when compared to local weather station apps. I can see lightning striking very close by and it says the lightning is several miles away. I contacted customer support who advised me to adjust the sensitivity but that created false alarms. I’ll live with it. I installed it below my weather station in the optional radiant shield. Looks cool! ... show more

    • Easy addition to your weather station
Plug and play. The 5000 found it automatically. We had thunderstorms the next day and I was amazed how many lightning flashes it recorded.

    • Ambient Weather products are of awesome quality!
Simple install and works perfectly! I just put batteries in the sensor and the base station just installed it on its own! I did get the mount to protect it and was able to mount it right with all of the rest of the sensors.

    • Works well!!
I was kind of skeptical about how well this would work, but surprised me! It detected lightning 24 miles away on the very first report of lightning. The distance they claim on this sensor is accurate. We’re having a thunderstorm now and it’s counted over 240 strikes!

    • Easy to setup! Good quality and best price too.
Good product. Seems well designed and easy to mount. The instructions are easy to follow and it found it self on my weather station without any interaction from me except for putting in the batteries. Super easy! Definitely recommend.
