SparkFun will be closed on Monday, May 30th, for Memorial Day. We will resume normal business hours at 9am (MT) on Tuesday, May 31st. Orders placed after 2pm (MT) on Friday May 27th will process and ship out on Tuesday, May 31st. From all of us at SparkFun, we wish you a safe and happy Memorial Day weekend!
The SparkFun Lightning Detector adds lightning detection to your next weather station to make sure you are aware of any potential hazardous weather heading your way. The AS3935 is capable of detecting lightning up to 40km away with an accuracy of 1km to the storm front with a sensitive antenna tuned to pick up lightning events in the 500kHz band.
There are a number of sources that can cause false positives but the lightning detector itself can reliably filter these out by default. If not, we've made sure to include settings you can configure using the lightning detector library to increase the chip's robustness to noise and false positives. The lightning detector library also gives you access to settings such as storm sensing sensitivity when detecting indoors vs outdoors, or the number of lightning strikes needed to trigger an interrupt.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Have tried it for a few days only. So far even in the presence of local visible lightning it is far less sensitive than I expected. SDR at 500 kHz sees lots of strikes but this module only reports occasional disturbance with no distance. Tried two sensitivity settings. Tuned within .6% of 500. Maybe I'm not using or mounting it well. Don't know what's wrong.
Edit: I installed a 2 meter USB cord and my issues with the Lightning Detector disappeared. I now get full range and efficiency and it does what the spec sheet says, via SPI. I upgraded my review to 4 stars.
Sparkfun has superior technical support for this product. The example software along with online documentation make it a snap to get it working and start learning about its features with an Arduino Uno. Non-Sparkfun third party support includes software and guides to work with Parallax Propeller P8X32A and Raspberry Pi. None are more helpful than Sparkfun.
My setup is Indoor and the factory SDR setting came in at exactly 500kHz.
So far I have tried more than 15 combinations of adjustments for Noise, Disturber, Watchdog, Spike and Lightning Threshold. I started with the default settings and gradually increased the settings one-by-one up to maximum. Each increased setting shortens detection distance.
The AS3935 sends many overhead lightning strike alerts when there is no lightning and when storms are many miles away. I get no Noise alerts and I ignore Disturber events.
Unfortunately, the AS3935 Lightning Detector is not fit for its intended use for me.
