Features 1、Detects both cloud-to-ground and cloud-to-cloud flashes 2、Estimates distance to strikes between 1km and 40km in 14 steps 3、Breakout board ships fully calibrated 4、Detection thresholds are programmable 5、Wide supply voltage range: 2.4V -5.5V Specification Description: Based on the AMS reference design, this is a breakout board for the AS3935 digital sensor. With a specially tuned antenna, SPI or I2C interfacing and a wide 2.4V to 5.5V standard operating range, this innovative sensor is designed to interface with most current development systems and boards. The breakout board features an inductor (antenna) specially designed for this application, This ensures that you don't have to write a massive back-end to support low-level IC calibration. Features: Detects both cloud-to-ground and cloud-to-cloud flashes Estimates distance to strikes between 1km and 40km in 14 steps Embedded "man made" disturbance rejection algorithm Detection thresholds are programmable (outdoor vs indoor, for example) SPI and I2C operation supported by default, I2C address 0x03 Breakout board ships fully calibrated Applications:Weather stations,Sports electronic equipment,Cell phones,Smart watches,Golf equipment Specifications: Model: AS3935 Size: 3 x 2.5 x 1.2cm/1.2 x 1.0 x 0.5inch Weight: 4g Package included: 1 x Sensor Package List
