DescriptionSound Detection Module Sensor for Intelligent Vehicle Compatible With Arduino is a Single channel signal output Sensor. The output is effective to the low-level sound signal with good fidelity, When there is sound, outputs low level and signal light. The module has both digital and analog outputs. A trimmer is used to calibrate the sensitivity of the sensor.
The High Sensitivity Sound Detection Module can be used for Acoustic control light, give sound and light alarm working with the Photosensitive sensor, and sound control, sound detect. (The Maximum induction distance is 0.5M).
Note: This sensor only recognizes the availability of sound (vibration principle) cannot identify the size of the sound or the specific frequencies of sound.
- IC Chip: LM393

- Single channel signal output
- The output effective signal is low level.
- Can detect the intensity of the sound environment
- With the retaining bolt hole, convenient installation.
Original order was missing 2 modules but seller was super understanding of the quantity mix up (they also sell individually so it was a simple error). They were very friendly and quick to send me the missing ones. All work great! Highly recommend.
These seem to work fine when connected to an Arduino UNO, however, I purchased them hoping to use with an ESP8266 and it seems that there is just too much noise for anything to really be picked up, you had to be basically inside the microphone. I was powering this from a 5v supply (with a common ground to the ESP8266) to ensure it was getting the correct power. I tested by connecting to an Arduino Uno and they seemed to work fine, not the best out there, but did what they were supposed to.
