Hello,
I would like to wake up my esp (in deep sleep) with a sound sensor.
Do you think it's possible ? It is not a high/low signal.
Thanks
It depends on the sound-sensor. Of course there are sound-sensors that switch between HIGH and LOW depending on the soundlevel. Most of these sensors can be adjusted at what level they shall switch.
And in case your sound-sensor has an anlog output a small OpAmp-circuit called schmitt-Trigger with hysteresis will do the job if inserted between sound-sensor and wakeup-trigger-input of the ESP32
Do you have an ESP32 or an ESP8266 and which exact board?
best regards Stefan
Ok I see. Do you have a link of this kind of sensor ?
I use a esp32 wroom-32d, devkitc_v4 board.
It's the model with digital and analog output I guess and I'll have to use the digital output
