* @brief SEN0290 Lightning Sensor
* @n This sensor can detect lightning and display the distance and intensity of the lightning within 40 km
* @n It can be set as indoor or outdoor mode.
* @n The module has three I2C, these addresses are:
* @n AS3935_ADD1 0x01 A0 = 1 A1 = 0
* @n AS3935_ADD2 0x02 A0 = 0 A1 = 1
* @n AS3935_ADD3 0x03 A0 = 1 A1 = 1
