HARDWARE LIST
1 Espressif Wemos D1-Mini
1 DFRobot AS3935 Lightning Sensor
5 Jumper Wires / Dupont
1 Breadboard (mini)

AS3935

 

The AS3935 is a lightning sensor IC. It can sense lightning that is from cloud to ground, or cloud to cloud, up to 40km (25 miles) away, in increments of 1km (0.6 miles) using a 500khz antenna. DFRobot created the breakout with everything needed on it, so there is no need for external parts to have the lightning sensor work. For more info, take a look at the data sheet. It can be bought on amazon or DFRobot.

Connections

 

There are only two parts, so the connections are nice and simple :).

 

D1-Mini - AS3935

-       -     GND

+      -     5V

IRQ  -     D3 (GPIO0)

D      -     D2 (GPIO4)

C      -     D1 (GPIO5)

Blynk

 

Blynk Setup uses only a few widgets. Three value displays and a terminal. You can also add a superchart to keep track of lightning strikes.
 

First, create a new project and add a device named "Lightning" (or whatever you like :) ).

Next, add widgets.

 

All the widget's settings are shown below:

Code Description

 

The entire code description can be found on the Hackster tutorial found here:

How to Use It

 

After uploading this code to your ESP8266, Blynk terminal should have information on it. To change a setting, type the setting you would like to change, into terminal. Then you will get a response asking for additional information for the setting you have chosen. Send the specified value, and the setting is changed! If the value you sent is not within the specified range, you will not get a response.
