Have been running the Earth Listener for a while now at firmware level 3.4.
Recently there were quite some thunderstorms here.
None of them were reported by the lightning sensor.
The sensor is reported in the serial monitor like this:
The value you should use with the EarthListener is 72pF, since that is being used on the board.
Detection of lightning is limited by insulators, such as the case. We therefore recommend to mount the VMA343 sensor outside of the EarthListener. There are small cuts in the case to wire the connectors to the inside. We will update the manual soon describing this option.
We can also suggest changing the setting indoor/outdoor, since the sensor seems to give better readings in the outdoor mode. We are still investigating this and will report in our manual with our findings.
On my unit, the problem is the same.
And I tested with a Piezo element from a sigaret lighter.
This should be the same as lightning. However no effect whatsoever.
I’ve seen a movie on Youtube, showing that a spark from Piezo-element has effect.

If you mimic lightning by using Piezo elements or other devices, we have choosen to hide this feedback from the sensor on the EarthListener. We do this because a lot of devices are giving off small electric discharges. However, if you connect the EarthListener to your PC and have a look at the Serial output, this feedback will be shown.
If you want that feedback shown on the EarthListener, change this line in the code:
Now every feedback from the sensor will be reported. Most of that feedback will fall under category 0: IRQ source result not expected. See tab functions in the code:
As it happens at the moment I am reconfiguring my Earth Listener to mount the sensor outside the box.
Gives also a simple opportunity to verify once more the connections.
Tomorrow we have another forcast with lighting so fingers crossed that no serious accidents happen and that we get an indication of the lightning.
Hi @vel342.
Also here, there has been a lot of thunder, but no reaction on the unit.
It doesn’t have to react to any electric discharge.
But it should react if there’s real lightning.
Right now, it seems that there’s never any reaction.
Showers with lightning have past (not far away) but no indication on the Earth Listener.
The situation was as the previous photo, running version 3.4 final.
What next (apart from waiting for more lightning)?
@VEL342,
Yes, the sensor is mounted at the back of the casing and visable.
However, if it’s that important, the sensor is not sensitive enough.
The house would shield too much, glass windows, concrete, wood etc may shield the fields.
How does my radio work inside my house?
In other words, I think the software has some filtering or a bug.
