The following parameters can be defined on the AS3935 Lightning Sensor:

Power Down
In power down mode (R0<0>=1), the entire AS3935 is switched off. The typical current
consumption is 800nA. After power up, the TRCO is not calibrated. The calibration must be
done by the user pressing the button “Calibrate RCOs”, and respectively “Calibrate LCO” if
needed.

LNA Settings
The LNA settings have to be changed according to the location of the lightning sensor
(outdoor vs. indoor) as described in the AS3935 datasheet.

Noise Floor
The threshold for the trigger of the noise floor interrupt can be selected via this drop down
menu. A bigger value sets the threshold higher.
