Hi Guys,
I'm new here, so apologize if this has already been covered. I would like to know when a vehicle that stops at the stop sign in front of my house just hangs out there for an extended period of time. I'm imagining a circuit with a ceramic mic, audio level detector that triggers a WiFi signal burst after the audio level has been continuously above a certain threshold for 2 - 3 minutes. I could design it myself, but someone else has probably done this already. Any hints or links would be appreciated.
