SEN0290 Lightning Sensor
This sensor can detect lightning and display the distance and intensity of the lightning within 40 km
It can be set as indoor or outdoor mode.
The module has three I2C, these addresses are:
AS3935_ADD1 0x01 A0 = High A1 = Low
AS3935_ADD3 0x03 A0 = High A1 = High
AS3935_ADD2 0x02 A0 = Low A1 = High
