Detect switching ON/OFF of Tube-light with a simple headphone jack

Now in our previous post, we established that the headphone jack can be used to successfully detect electromagnetic disturbances ( Sparks and Lightning ). In this post, we explore the interaction of the tube light with the headphone jack.

Here is a close up of the peak that you saw in the video:

Nowadays of course, we have moved on Non-flickering tubelights and it is highly unlikely that we might be able to detect the peculiar peaks that you see on this. But to be sure we are currently working on this and we will keep you guys posted on the results.

Also if we could incorporate this into a IoT network, things will go crazy!!!
