I was recently introduced to fully integrated lightning sensor ICs: https://www.digikey.com/en/product-highlight/a/ams/as3935-fr... - supply it a repurposed RFID coil and it will tell you when it detects lightning and how far the storm front is. I have one in my weather station just for fun, but it's a highly practical device for golf courses, swimming pools, sporting facilities, etc. where knowing how far away lightning is is operationally important.
