Lightning Sensor 06045
  1. Good inexpensive detector. Interesting to see counts and distances of the lightning strikes. review by Scott on 7/13/2017

    I'm quite happy with the lightning detector - it definitely works well. I use it mostly with my 06058M console. The console is required if you want to see the count of lightning strokes and the estimated distances. On the other hand, you can take just the detector on camping trips or golfing, etc. and get an audible warning if lightning is within 20-30 miles. It easily fits in my pocket. This is probably a must-have for outdoor sports officials. Much better than watching for lightning while trying to officiate a game.

    The beep is fairly loud, so you might not want to keep it in your bedroom. It only beeps for the first 10 strokes, but it will probably wake you up. After than, the red light flashes with each detected stroke and a large red light on the bottom stays lit until no new strokes are detected for two hours. It seems to work reasonably well even indoors, but I ended up putting it in a zip-lock bag and tacked it to to wall on the outside of the house, under the roof overhang. Probably wouldn't need the plastic bag, it seems to be fairly weather resistant. The detector also has a temperature and humidity sensor, which probably wouldn't work well in a plastic bag, but I don't use those sensors anyway - the 5 in 1 unit on the roof already has those.

    It's nice getting an advanced warning of approaching storms. As the distance of the strokes decreases, you can get a feel for how fast a storm is approaching. When the distances start increasing, then you know the storm has come as close as it's going to come.

    A few observations:
    Seems to be very (overly?) sensitive. The average storm gets hundreds of lightning strokes counted by the detector. I don't hear thunder for most of the detected lightning strokes. I wouldn't have thought there'd be so many! Maybe it counts even "small" lightning strokes, if there is such a thing, that don't produce much thunder, that I'd normally not notice. Or possibly a large stroke gets counted as several strokes. The exact number of strokes isn't important though, it just gives you an idea of how much lightning is happening.

    It often warns of interference, even when the detector is outside away from anything that could interfere, but usually only when there's a storm. Still seems to work fine - despite the interference. This also makes me think it may be a bit over-sensitive, possibly mistaking lightning strikes for interference sometimes? The (false?) interference warnings only last for a few seconds so it's really no problem. If I put it near a cell phone, or in a car, the interference warnings last much longer, likely indicating a real interference problem. I think the interference detecting function isn't perfect, but it certainly works well enough.

    I've read that inexpensive detectors use the strength of the stroke to estimate distance. If the strokes vary much in intensity I would think a "strong" stroke would be judged closer than a "weak" stroke, even if they were the same distance away. It doesn't seem to be a problem with this detector. The estimates seem consistent - relative to each other. In other words, when a storm approaches, the distances start at about 20-25 miles, a few minutes apart and gradually and smoothly decrease to 1-5 miles, every few seconds. Then, they gradually increase again to 20-25 miles, just as you'd expect. If the distance estimates were wildly inaccurate, I would expect that there wouldn't be that consistently decreasing value as the storm approaches and increasing values as it goes away. Note again that you need a console to see the distance estimates and counts.

    Definitely worth the money - it works surprisingly well and integrates nicely with the console.

  2. Great Little device review by john on 7/13/2017

    After having a Boltek lightning detector for many years I wanted to have something not attached to a computer and easily portable and I must say this unit really works well. So far it has shown it can detect a storm 50 miles away and alerts me when it close as I had a bolt strike right over the house. It connects easily with my bedside HD display and I couldn't be happier. I would recommend to anyone who is a weather nerd like myself or just to have when you go out camping or any other activity that you need to monitor lightning for a dangerous situation .

  3. Not bad but not great either... review by Mike on 7/6/2017

    Detector definitely does it's job of warning of lightning in the area (312 strikes detected in early summer storm last week). Unfortunately, and as many others have reported (search Acurite Lightning Detector 'Unable to Detect') during a storm the 'Unable to Detect' message is displayed on the HD display. Yes, I have placed this EXACTLY to Acurites recommendation; in fact it's now in the middle of my yard 30' from the nearest electrical device - yet still the message appears but only during a storm? This has done nothing to reinforce my confidence in this device but it does still appear to count strikes once connection has been reestablished. At the end of the day, it's a $20 detector, it might be not perfect or 100% reliable but it's better than nothing!

  4. Great to have advance warning. review by Jack on 5/6/2017

    Great to have advance warning of an electrical storm. Gives you time to get things taken care of and inside, and reduces the chance of a lightening strike. The hardest thing about it, was installing the batteries, (it was easy). I would purchase again.

  5. Not just a lighting detector review by David on 5/4/2017

    Funny the instructions never mention it but this unit also has temperature and humidity sensors. It powered up and connected to my indoor display immediately unlike the rain gauge which had to have it's little micro switch for the frequency band switched back and forth a couple of times before it synched up.

  6. lightning detector review by frank on 3/28/2017

    I have had several lightning events with this detector and it works very well. I have it enclosed in a waterproof electrical box about 15 feet above ground. It appears the range is much father than the 25 mile range advertised.

  7. Clear, Crisp Display review by John on 3/20/2017

    This was a replacement display for the one that came with my 5-1. This is much cleaner, crisper and very easy to read even from a distance. I like the almanac feature as well as the at a glance weather information.

  8. Nice Design review by John on 3/20/2017

    Just purchased, so no opp yet to see how it functions. Have it on a tree (for now) looking forward to an active t-storm season to see how well it works.

  9. Great product, works well! review by MikeN on 2/21/2017

    So far this works really well with my new 06058M HD Display. Does what it claims, and really surprised it works this well. I had a couple lightning storms this week and as soon as I heard the thunder it showed up on the display. Pretty amazing. For the price I would definitely recommend this product.

  10. Great Tool review by Ryan on 2/17/2017

    I love this little sensor, it seems to be very accurate. I like the fact that the bottom of the screen turns red (HD extra display) and it starts counting the strikes right away. I like that it has a strike count after the storm has passed and gives you a distance from the strikes as well. I am going to push to get these installed at all of my neighborhood pools. There are always arguments between the people at the pools and my lifeguards about how long ago the last strike was. This takes the guesswork out of the equation. Great sensor, I can't wait until they can get integration with the smartHub.

  11. Lightening detector review by ddh@pacwest.net on 2/2/2017

    This device is a great idea but fails to live up to its promise. Yes it does detect lightening however it is supposed to also transmit temp and humidity. This aspect is totally non functional with any of your hiend dispalys. Not does it function with My acurite. From what I have so far learned is that if you want full function you have to purchase a dedicated display just for it. All in all a disappointment. I love AcuRitee products but this device has beenproblamatic.
    Respectfully Submitted,

  12. Integration with Hub review by John on 9/16/2016

    The product is fine. Works as advertised. Limited use however as it is not integrated with the hub, preventing remote monitoring and alerts. Great idea, half a solution.

  13. Works Almost as Good as a Terrier review by Douglas on 9/9/2016

    My Wheaton Terrier alway lets us know of approaching storms. I bought this detector to see how acurate she actually is, and they are nearly a match. The other night the news had predicted stirms here in Iowa, and just minutes after my terrier started to whine, the detector went off. I'd have to say the unit works very well based on the Weather Dog scale. Even though the pup won buy seconds this unit id much, much cheaper. I give it ****'s. Doug in Des Moines, Ia
