Dog bark sensor
Hello! I'm looking to experiment with a DIY dog bark control/training system, but I'm not sure where to start on the bark sensing front. I know that commercial bark control collars (don't worry -- I'm not building a shock collar) use a combination of mics and vibration sensors together to reduce false positives and prevent the system from triggering if it is another dog doing the barking. Any ideas how I could build something that performs a similar function?
