DFRobot_AS3935

AS3935 Lightning Sensor can detect lightning and display the distance and intensity of the lightning without the disturbance of electric arc and noise. It can be set as indoor or outdoor mode.

Table of Contents

Summary

Input commands and read data from AS3935 modules

  1. Lightning sensor warns of lightning storm activity within a radius of 40km
  2. Distance estimation to the head of the storm from overhead to 40km in 15 steps
  3. Detects both cloud-to-ground and intra-cloud(cloud-to-cloud) flashes
  4. Embedded man-made disturber rejection algorithm
  5. Programmable detection levels enable threshold setting for optimal controls
  6. Three i2c interfaces, switch freely to avoid site conflicts

Installation

要使用这个库,首先将库下载到Raspberry Pi,然后打开例程文件夹。要执行一个例程demox.py,请在命令行中输入python demox.py。例如,要执行control_led.py例程,你需要输入:

python DFRobot_AS3935_detailed.py
