LM393 Sound Detection Sensor Module for Arduino detects whether sound has exceeded a threshold value. The sound is detected via microphone and fed into an LM393 op-amp.
The sound level setpoint is adjusted via an onboard potentiometer. When the sound level exceeds the set poi..
This small breakout board couples an Electret microphone (100Hz--10kHz) with a 60x mic preamplifier to amplify the sounds of voice, claps, door knocks or any sounds loud enough to be picked up by a microcontroller’s analog-to-digital converter. Each breakout comes fully assembled and works fro..
