Do you know what the reaction time on the module is? I've been looking at this sensor for a while, wondering if it's fast enough to record a timestamp to within a few microseconds, and use a few locations to triangulate the source.
From the Datasheet it states that 'the shortest time span between two lightning strikes that the AS3935 can resolve is approximately one second'. It will go faster if you turn off that Disturber Detect Feature and Distance Estimation. Triangulation is definitely something I have thought about and I reckon it would work. Also this video at from 2:21 is a very Rad Demonstration - ua-cam.com/video/tyJ3ctWfYfk/v-deo.html
Lots of details but lacking practical instruction on how the module detects lighting for the beginner, I cant see an antenna or is it the information collected from an online data provider.
Wow! This is amazing! Looking forward to seeing someone connect this to an esp32 and sending alert notifications to a phone, perhaps via Callmebot. Would be terrific for hiking if there was a way to establish! a Bluetooth connection with a phone when there is no internet available.
Glad you dig it 😊 here is a very well-documented project using an ESP8266 and the AS3935-based Franklin Lightning Detector -> github.com/shred/kaminari Not quite what you want but we are getting closer and closer with our fully open source scripts.
Wow that little module is simply awesome! Merry Christmas to all at Core Electronics and thank you for the insanely awesome videos this year - I don't know how you will better it in 23 but I'm sure you will!
Yep, I'll pay that one. How "large" a Pi does it need? Lightning doesn't worry me at my desk, add a 5V supply, a small screen and you have a very useful, potentially lifesaving, tool when out bushwalking, swimming in a dam or outdoor pool, walking The Grampians peaks, etc. Nice. Please revisit this sometime and put together a "small as you can make it" low power portable unit. BLE to a phone maybe??
It is such a rad device. And I absolutely love the idea of increasing the portability of it. Here is a very exciting Github project of an ESP8266 the AS3935-based Franklin Lightning Detector -> github.com/shred/kaminari It connects to a WiFi network and offers a JSON web service for detected lightning strikes.
Wow I need to get one of these we get lightning all the time in the summer monsoons I'm in Arizona. One time I was sleeping, and it was so loud the noise actually echoed in my home. I knew it was close the light lit up my room like it was daylight I could see everything for a few MS. Turned out it hit a palm tree in my neighbor's yard it was on fire. Fire department was called but by the time they got there the top of the palm tree was just about out and entire thing burned up. The next day it was just a stick sticking up he had it removed.
I’m gonna get one! Thanks for this! BTW- there is actually a 4th kind of lightning, ground to cloud lightning, very rare, but it does occur. I’m guessing the dfrobot registers this as cloud to ground? 👍
Very interesting mate! I didn't know about that at all. And I guess it would, but we'd have to test it. I also know of another weird lightning phenomena, Ball Lightning but Wiki tells me its unproven - en.wikipedia.org/wiki/Ball_lightning
Is there any way to add direction finding to this other than triangulation? If triangulation is used, how far apart do you think detectors would need to be? Also, I’m loving the clarity, brevity, and method of explanation and presentation on this channel so far!
I know this is an old comment, but I was just wondering the same things, and I imagine direction finding could be done by hooking up directional microphones and having them compare how loud the thunder is, otherwise the module seems to have an antenna on board for picking up the lightning strikes, if you could make a directional antenna tuned to the right frequency you could do something similar to the microphone idea
Can you add a Nextion screen to the Pi so an external monitor is not needed? It would streamline the package down into a simple enclosure and perhaps add the UPS Hat to power the unit. This would allow the user more flexible usage around the home or in the car. Even a simple Bluetooth mini keyboard to program on the fly.
Currently the SparkFun Lightning Detector (AS3935) is not on the list of compatible boards with the SparkFun OpenLog Artemis board. Sparkfun assures me more boards are being added all the time to the compatibility list. I reckon its only a matter of time. Here is their Sparkfun Artemis Forum, ask there and I bet you will recieve 😊 they're good people - forum.sparkfun.com/viewforum.php?f=167
So with the one second delay it is probably not fast enough to hook it up to a camera and take pictures of lightning that way? Especially with the overhead of a raspberry and python?
I dig it, it must pull the lightning strike data from a website like this - www.lightningmaps.org/. I'd love to be able take our live discoveries data we pull from these modules and update information into that service.

Worth noting, at the moment of lightning, the interrupt pin IRQ generates a pulse. That pulse can be used to trigger a Camera shutter to open, helping photographers to accurately capture the exciting moment of lightning.
Respected sir, I need some technical clarification on why AS3935 is tuned to 500khz only and why not other frequency. Is 500khz related to lightning radiation
How would you connect this to home assistant? Would be awesome to have it home tell us that a storm is coming with the program running locally instead of relying on online sources that update every x minutes...

Totally all happens on the board. Data is collected on the edge, this board doesn't have any online connection.

Brilliant vid thank you

Thank you
Thank you for this.. helped me up and running
Will the code allow you to convert to Miles?
You can definitely customise the Open Source Script and you'll get it outputting miles within no time 😊
Is there somewhere you can automatically upload this data to contribute to weather information?
Not yet but this does exist so I am hopeful that soon we will be able to - www.blitzortung.org/en/live_lightning_maps.php
plz reduce mic gain just a tad bit next time :D
good tutorial though, thanks
Shaddap and take my money!

What is it called? I am curious.

Interesting. I wonder if this could be hooked up to a camera to trigger its shutter? What do you guys think?
Let me know if you find out. That would be great.

Where is the data sheet? I'll be connecting to a PIC and writing my own code in assembly. Who downloads other people's code?
