|
* On The Lightning Sensor
|
|
* This sensor can detect lightning and display the distance and intensity of the lightning without the
|
|
* disturbance of electric arc and noise.It can be set as indoor or outdoor mode.
|
|
* The module has three I2C, the addresses are:
|
|
* 0x03 A0-High A1-High
|
|
* 0x02 A0-Low A1-High
|
|
* 0x01 A0-High A1-Low
