The Thunder Watcher.

This device can sense the approach of lightning within several dozen kilometers, and make an alert to hide.

Early warning indication of lightning storm activity within a 40km range.
Provide you distance estimation from a overhead thunderstorm.
Detects both cloud-to-ground and intra-cloud (cloud-to-cloud) flashes.
The intelligent algorithm provides for false disturber rejection.

Description

The Thunder Watcher is a programmable Wearable Device that detects the presence and approach of potentially hazardous lightning activity in the vicinity.
It detects intra-cloud activity as well as cloud to ground ashes, often enabling risk to be evaluated for approaching storms.
The AS3935 IC detects lightning activity as it approaches from up to 40 km away, which provides a much longer distance for lightning warning.

Demo

Requirement

Usage

Turn on the power switch.(Initialization is started.)
You have to wait for a thunderstorm.
When a thundercloud is detected, the LED will light up. And the distance to the thundercloud is displayed on the LCD display.
If thunderclouds are near, evacuate to a safe place.

Importing a FreqCounter Library

Lab3 - Laboratory for Experimental Computer Science

In the Arduino IDE, navigate to Sketch > Include Library.
At the top of the drop down list, select the option to "Add .ZIP Library''.
You will be prompted to select the library you would like to add.
Return to the Sketch > Import Library menu. You should now see the library at the bottom of the drop-down menu.
It is ready to be used in your sketch. The zip file will have been expanded in the libraries folder in your Arduino sketches directory.

Importing a ST7032 Library

tomozh/arduino_ST7032- Arduino Liquid Crystal compatible library

When you are on arduino_ST7032 project page, you press the 'Download ZIP' button which is located under the "Clone or Download" drop down.
This allows you to download the most recent version of the code as a zip archive.
Down list, select the option to "Add .ZIP Library''. You will be prompted to select the library you would like to add.
Return to the Sketch > Import Library menu. You should now see the library at the bottom of the drop-down menu.
It is ready to be used in your sketch. The zip file will have been expanded in the libraries folder in your Arduino sketches directory.
