Hi all! I’m trying to make sense of the SparkFun Electret Microphone Breakout, BOB-12758. I’ve got it connected, and read values through ADC… but am I doing it right? The voltage mostly stays around 1.6, but spikes to 2-3 with no apparent reason. I’m using an ADC pin on an ESP-WROOM-32 devkit. My goal is to detect prolonged loud noise and activate an automation in Home Assistant based on the input from this mic. Any tips for a more sensible configuration to capture output?
sensor:
- platform: adc
pin: 32
name: “Sound level”
update_interval: 500ms
attenuation: auto
