Sr04 like device works to 300ft Answered
An sr04 has a max range of 12'. I need to range to 300'. Residential well, 8" pipe. Aprox. 150-300' to water. A pinger and mic? A sr0400? Can not drop rocks or physically go past 6" below pipe cap. If I can find said device I'm thinking connect to a LoRa. We want to monitor say 12 wells in a square mile.
