AMS AS3935 Digital Lightning Sensor Breakout Board
(Arduino compatible, fully calibrated)

Description:
Based on the AMS reference design, this is a breakout board for the AS3935 digital lightning 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. This includes all of the current Arduino modules! The breakout board features an inductor (antenna) specially designed for this application, and the board ships fully calibrated. This ensures that you don’t have to write a massive back-end to support low-level IC calibration just to get started - focus on your final application! 

Don't want to wait for a thunderstorm to test your setup? We now make an Arduino Shield to "emulate" the signature of lightning strikes specifically tuned for the AS3935 sensor! See our SEN-39002 listing for the emulator and kit purchase discount options.

*We store calibration values for each board shipped. This information can be provided at your request by simply emailing us with your order reference number. Contact info can be found below. Example code can be found on Github in both I2C and SPI flavors. Additional information is available upon request, including help with your application!
