The StemeduLM393 Sound Sensor Module is a high-sensitivity microphone sensor designed for Arduino applications. Operating at 3.3-5V, it uses an LM393 op-amp and an electret condenser microphone to detect sound levels exceeding a user-set threshold. Featuring an onboard potentiometer for sensitivity adjustment and an LED indicator for real-time sound detection, this pack of 5 modules is ideal for scalable sound-triggered projects and prototyping.

Nice sound detectors
I am trying to make an audio detector for predator animals which evade motion detection. I got the Stemedu Sound Sensor Module kit to explore the idea of detecting sounds of an animal movement above a certain threshold to indicate the presence of the animal close by. This works great in the lab but does not do as well outdoors where I want to use this idea. I have no problem with the quality of the product and it comes with a nice bundle of jumper wires.

Great microphone for Arduino/Raspberry Pi
Great quality and cheap!

Great module for a knock sensor
Looking to build escape room devices?You can use this sensor to listen for people knocking on doors, or making sounds louder than a specified level.To set it up, power it up. Then turn the potentiometer until the LED turns on, then turn it the opposite way until it turns off. Load the sketch, and you are ready
