how to use k10 mic to monitor environment sound level
alo.takeda 2026-04-04 10:15:42 941 Views1 Replies hi,
I'm searching for a way to my K10 to monitor the sound level of my room, and to react with an action when the sound level gets above a certain level.
but when I check Mind+ and the docs here https://www.unihiker.com/wiki/K10/Examples/examples_mpy/#on-board-sensor-record-play I only find examples for recording and playing back.
I wanted to do something like this first:
https://microbit.org/projects/make-it-code-it/sound-meter/
and preferably using MicroPython, if possible.
Hi there!
The built-in microphone on the K10 only supports audio recording, and cannot directly detect or output the sound level/volume value.
To monitor the room sound level and trigger actions when the volume exceeds a threshold, you can connect an additional sound sensor (DFR0034) to the K10, and you can implement this function with MicroPython.
