Lightning/Thunder detector

Reported by: Musti Owned by: Musti

Blocking: Effort: normal
Blocked by: 1023, 1098 Security sensitive: no

Description

Construct a 1-wire lightning detector. The circuit has to:

  • 1-wire interface
  • detect amplitude and direction of EMP pulse
  • log the amplitude and direction with exact time.
  • sync RTC with external source daily

Could use http://www.maxim-ic.com/datasheet/index.mvp/id/4105 and crossed loop antennas.

The detector could be constructed using an ATtiny microcontroller that simulates a 1-wire device and detects/logs lightning strikes.

  • Keywords projectideas, sensor added; projectideas removed
  • Summary changed from 1-wire lightning detector to Lightning detector

comment:3 Changed 7 years ago by Musti

  • Status changed from new to assigned
  • Blocked by set to 1023

Due to the availability of better solutions 1-wire lightning detector as such should be depreciated and not even developed.

AS3935 Franklin Lightning Sensor IC should be used insted in conjunction with Node monitor circuit #1023

This IC is simply interfacable via I2C and is straightforward to implement, however as suitable 500kHz magnetic loop antenna should be designed. The IC datasheet can not be published here, available upon request from the manufacturer.

  • Component changed from hardware to telemetry

AS3935 samples are expected this week, I should have a prototype finished in a weeks time.

In c7c488482cdaedaed5442b9b7aca43b8b5aa33b8/telemetry:

For use with AS3935 lightning detector for tuning. See #893

Connect with the European Storm Forecast Experiment, when we are finished?

Awesome, so this could be user (with enough nodes) to even see where from are thunder storms coming from and their force (emp) ?

I'll put this on each of our nodes that are on top of buildings as soon as they become available ;)

Each detector gives an approximate distance to every strike (up to 30km) and a relative measure of EMP power. Direction can be determined by means of triangulation, however that will not be supported yet as some precise timing is required.

I heard that sound triangulation is quite easy to implement, maybe even easier than EMP? Could we use both?

comment:12 Changed 5 years ago by valentt

Do you know about Blitzortung.org ?

They have ready do use diy or prebuild system for thunder/lighting detection.
They use GPS for time sync their servers do triangulation, and if it is positioned correctly, they have amazing accuracy which is often around 100m or less!

This is their map but with same data from Blitzortung Lightingmaps maps are also created.

How about we use their hardware and software platform and especially their domain knowledge instead of reinventing the wheel? What are your thought on this?
