I would like to wake up my esp32 (in deep sleep) when the sound sensor detects a sound. The output of the sensor is not 0/1 but a voltage value, according to the sound level. Is it possible to do this ? I've tried with this code but it is not working. After going to sleep...
I want to build an alarm system. Where I use the KY-038 sound sensor and it sounds the buzzer. Unfortunately, I can't find a connection diagram with the ESP32 and KY-038 sound sensor anywhere. Can anyone help me how to connect it and with a simple code?

Experiment with the controls. You must start the stream manually; it does not start automatically. The camera performance is on par with the ESP32-CAM, which makes sense as both boards use the same 2 MP sensor. Voice Recording Camera Today, we will perform an experiment, one that could ...
between the ultrasonic sensor and the object which we place in front of the sensor. Higher is the distance, the higher the time sonar waves will take to reach back to the ultrasonic receiver circuit. Because ultrasonic waves travel through the air with the speed of sound and speed remains ...
