# 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
