Sensing lightning with an AS3935 Franklin Lightning Sensor and an ESP8266 #Weather
shred.zone documents building a lightning detector using an AS3935 Franklin Lightning Sensor.
The sensor module can be found at many online shops selling products from China. It is not really cheap, but still affordable. I decided to use an ESP8266 as microcontroller, so I can read the sensor data by WLAN. The sensor is connected to the ESP via SPI. There was also some space left for a SK6812 RGBW LED indicating the sensor status.
The result of this project can be found at GitHub. It’s called Kaminari (which is Japanese for lightning), and also comes with OpenSCAD files for a 3D printed, pyramid shaped case with illuminated tip. In this article I will explain a bit about how I developed the Kaminari firmware.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
