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.
