Hello all, me and my group are working on a senior design project and for part of our project we are trying to make a glass break sensor that has far less false alarms. To do this we have plans to use an ESP32 and a microphone to detect the sound of the glass breaking. It will then go through a pattern recognition process to compare the audio file to known glass break signals stored on a micro SD. However still in the design phase this process seems to use a lot of power.
We had thoughts of placing the MC into a sleep mode and waking it using an interrupt if a suspect sound file is sent. We are wondering if anyone has any ideas how this could be done. We have suggested using a second lower power MC for the initial screening of the sound and the esp32 for the final decision.
