The AS3935 is a programmable fully integrated IC Illumination Sensor that detects the presence and approach of hazardous potential illumination activity in the vicinity and provides an estimate of the distance to the head of the storm. The integrated lighting algorithm checks the incoming signal pattern to reject possible man-made disturbances.
The AS3935 can also provide noise level information and inform the external unit (eg microcontroller) in high noise conditions, with the noise floor generator and noise floor evaluation blocks.
The AS3935 can be programmed through a standard 4-wire SPI or an i (c. In addition, if the latter is chosen, it is possible to choose between four different directions. Two clocks are generated by two different RC oscillators: TRCO and SRCO.An automatic procedure can increase the precision of those oscillators.The AS3935 can be supplied by an internal voltage regulator or directly by VDD.
AS3935 is ideal for Weather Stations, Watches, Sports Equipment, Laptops, Pool Safety, Uninterruptible Power Supply (UPS), Global Positioning System (GPS), Mobile Phones, Watches and Golf Equipment.
