Product Description: Based on the AMS reference design, this is a breakout board for the AS3935 digital lightning sensor. This innovative sensor features a specially tuned antenna, SPI or I2C interfaces, and a wide standard operating range of 2.4V to 5.5V, designed to connect with most current development systems and circuit boards. The breakout board includes an inductor (antenna) specifically designed for this application, ensuring support for low-level IC calibration without the need for extensive backend coding. Features: Detects cloud-to-ground and cloud-to-cloud lightning Estimates lightning distance in 14 steps ranging from 1 km to 40 km Embedded "artificial" interference suppression algorithm Programmable lightning detection threshold (e.g., outdoor vs. indoor) Wide power supply voltage range: 2.4V-5.5V Default support for SPI and I2C operation; I2C address 0x03 Fully calibrated on the breakout board Applications: Weather stations, sports electronics, mobile phones, smartwatches, golf equipment Product Specifications: Model: AS3935 Voltage: 2.4V - 5.5V Color: Purple Material: Plastic+Metal Package Contents: 1*module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
