This is a nice gimmick which detects EMPs (i.e. when lighting takes place). There are many sensors around, to detect all kind of things. However, detect lighting strikes is a complete different area. Use this sensor for :
:[short story]: Get kids back to outdoor trainingsessions and other reasons.
:[long story]: For an outdoor sport, I was requested to develop a lightning detection system. Some parents cancel trainingsessions for their kids, if there is a chance for rain / drizzle. When asked for detailed motivation : "saw a video at YouTube". Sporters at an open field got injured, when lightning struck nearby. Fair enough and I designed this sensor. Nowadays, when lightning is detected within a 30 km radius, an outdoor trainingsession will be aborted.
Once I got in contact with a hobby photographer. The question raised if the sensor could trigger a camera (Canon EOS something), to shoot pictures about storms / lightning. It does, with some additional electronics (relay, rechargeable Li-Ion battery). I can confirm he shot some excellent pictures about lightning phenomena (note : camera should be set into the correct direction).
I knew someone who got his home automated (domotics). Once lightning took place nearby, several devices (i.e. computer and TV) got unrepairable damaged. He asked : "Can it operate for an early warning-system ?" I can inform you, today the sensor is connected to a domotics system. As soon as lightning is detected, all sensitive equipment will be cut off the grid.
These sensors are also used at several space and nuclear research affiliated organisations. It is confirmed they do the job as required, but no further info shared. Today, I'm still not sure for what purpose. I guess it's behind secret doors and I'll never get to know the details.
Sure, there are some sensors available. They operate stand-alone or it's just a tiny IC. A tiny IC requires an additional design, including a special antenna, microcontroller and alike.
However, this sensor is easy to use / implement. When an EMP (lightning) is detected, an audible beep can be heard and a LED will flash. Need such sensor as trigger ? Use digital output. Need it to study details about EMPs ? Use analog output. In other words, this is a very versatile sensor. For a datasheet (PDF, size : 676 kb), just click >here<.
This sensor can be battery operated, is small, easy to use for many projects and low cost. It's definitely something for you !

About 20 years ago I finished my study Business Management (B.Sc) including a background in Chemistry. During my study I assembled / repaired computers, designed web-pages to get some money to burn. When I finished study I became a software engineer (Oracle and Visual Basic) and worked for several large companies. In 2002 I got in contact with a small business in dental healthcare. Their request was to develop a software-tool for their whole business : keep track of sales, stock, working procedures, Human Resource and alike. Spending time at each department, I figured out what they needed. Developed it from A to Z. I even had to design the carton package for it (am still proud of it). It was a wise lesson. It provided very good experience, to run such a project on my own.
After a while, the software-tool required an encryption hardware key (kind of USB-stick). Oh man, this was my real introduction into the world of electronics. I loved it, looking for more and more input, gaining experiences. It was the moment I felt :" I can create whatever I want". It's a mighty feeling !
Back in those days, electronic shops were still scarce. Whenever I needed something, most of the time they didn't even had it in stock. I had to pre-order it. Next, I noticed I could order components at a far better price, in large quantities, abroad. Those were the days internet-shops popped up. It made me order all kind of components. After a while I stocked 1.000.000+ components.
If I look back now, it's hard to say : "I'm just a hobbyist".
Research and Developement is where my heart is. Whenever I notice an electronic device lacks a certain functionality, it peeks my interest. Same goes for tools which don't exist yet, but I wish there was "something" available / for sale. That's the moment you'll see me absent minded. I'm searching and crawling for solutions (even outside the box), start with raw ideas, create prototypes and tinkering. And when ready,... use it.
When creating prototypes or final versions, I often end up with 10 pieces (minimum). And exactly this is where selling at internet (i.e. Indie) steps in.
So what am I ? If I can't come up with a straight and short answer, people mumble : "Creative problem-solver". I think it's a good description. I can stick with that.
