Today, I want to show you how I connect sound sensor like below to my home made Environment sensor.
This sensor is a dumb sound sensor. It detect sound or “no sound”. It is not sound metering device. It is not a voice recognition device. This is good for adding information in detecting presence.
I want to try something different. I will be connecting 3 of them at one time using “or gate”. I got the inspiration from devices like google home and amazon echo. They use multiple microphones to cover wide are of room.
Below is the prototype with just rudimentary wiring. Once I am happy with the setting, I might consider making board to make connection to the home made sensor tidy
Here is a short demo.
