I've a project in my mind and I need some clarification in order to know if is possible or not develop it using Arduino. I'm looking for the very first consultation/help...
Part of the project consist in an Arduino board which has to detect when a specific sound is emitted in a pretty quiete and small room. The sound in question is very similar to a small waterfall or the sound of a shower. (basically i'm referring to the sound of dropping water)
When the sound is detected, then the Arduino 'll start a countdown (I'v no problem at all in developping this part )
Regarding the "sound detector", do you have any advice regarding which sensor to use?
Any kind of link, video, tutorial and so is more than wellcome
Showers and waterfalls produce something very close to white noise...the sound covers a wide range of frequencies.
So while it will be easy to discover that the total sound level in the room has increased, using a sound level detector like a KY-037, narrowing the cause down to that specific type of sound may be tricky. You could check that the sound lasts a while to exclude sharp, short sounds like claps and footsteps but I'm not sure what else you can easily do. I guess it depends what other sounds there may be in the room.
