Lightning Detector – AS3935 閃電探測器 颱風 氣象偵測

可為您的氣象偵測站添加雷電檢測功能,以確保您了解任何潛在的危險天氣。AS3935能夠探測距離最遠40公里的閃電,精確度為風暴前方1公里,並配有靈敏的天線,可以調節500kHz頻段內的閃電事件。

有許多錯誤來源可能會導致誤報,但閃電探測器本身可以在默認情況下可靠的過濾掉這些誤差。如果沒有,我們確保包含您可以使用閃電探測器庫配置的設置,以提高芯片對噪聲和誤報的穩健性。雷電探測器庫還可讓您訪問室內與室外探測時的風暴感應靈敏度,或觸發中斷所需的雷擊次數。

=========================================================

 

The SparkFun Lightning Detector adds lightning detection to your next weather station to make sure you are aware of any potential hazardous weather heading your way. The AS3935 is capable of detecting lightning up to 40km away with an accuracy of 1km to the storm front with a sensitive antenna tuned to pick up lightning events in the 500kHz band.

There are a number of sources that can cause false positives but the lightning detector itself can reliably filter these out by default. If not, we’ve made sure to include settings you can configure using the lightning detector library to increase the chip’s robustness to noise and false positives. The lightning detector library also gives you access to settings such as storm sensing sensitivity when detecting indoors vs outdoors, or the number of lightning strikes needed to trigger an interrupt.
