SEN-39003 AS3935 Lightning Sensor Qwiic Breakout
Overview
The SEN-39003 is an evaluation expansion board featuring the AS3935 Franklin Lightning Sensor, designed to detect the presence and distance of potentially hazardous lightning activity. It provides a pre-calibrated sensing solution that calculates the distance to the head of a storm up to 40km away. This board utilizes the Qwiic connect system for easy integration and supports both I2C and SPI communication protocols.
Why Choose This Part
This breakout comes fully calibrated with calibration values stored in memory, eliminating the need for complex RF tuning during initial setup. Its wide operating voltage range of 2.4V to 5.5V and dual interface support make it compatible with a variety of 3.3V and 5V microcontroller platforms.
Applications
Key Specifications
Getting Started
Connect the board to any Qwiic-compatible microcontroller or use the 0.1-inch header pins for standard breadboard wiring. Engineers should use the provided Arduino or Python libraries to read distance estimation and lightning intensity registers over I2C or SPI. Ensure the board is placed away from local EMI sources like switching power supplies or brushless motors to prevent false positives.
