1 General Description
The AS3935 is a programmable fully integrated Lightning Sensor IC
that detects the presence and approach of potentially hazardous
lightning activity in the vicinity and provides an estimation on the
distance to the head of the storm. The embedded lightning algorithm
checks the incoming signal pattern to reject the potential man-made
disturbers.
The AS3935 can also provide information on the noise level and
inform the external unit (e.g. microcontroller) in case of high noise
conditions, with the noise floor generator and noise floor evaluation
blocks.
The AS3935 can be programmed via a 4-wire standard SPI or an
I²C. Also, in case the latter is chosen, it is possible to choose among
four different addresses. Two clocks are internally generated by two
different RC-Oscillators: TRCO and SRCO. An automatic procedure
can increase the precision of those oscillators. The AS3935 can be
either supplied by an internal voltage regulator or directly by VDD.
