Description
A sound sensor is defined as a module that detects sound waves through their intensity and converts it to electrical signals.
The sound detection sensor module for Arduino detects whether the sound has exceeded a threshold value. Sound is detected via microphone and fed into an LM393 op-amp. The sound level set point is adjusted via an onboard potentiometer. When the sound level exceeds the set point, an LED on the module is illuminated and the output is sent low.
Features and Specifications:-
- An detect the intensity of the sound environment, use note: the sound sensor can identify the presence of (according to the principle of vibration) or a particular frequency of sound does not recognize the volume of the sound
- Sensitivity adjustable digital potentiometer to adjust (blue)
- Operating voltage 3.3V-5V
- Outputs digital switching output (high and low levels 0 and 1
- Operating current (Vcc=5V): 4-8mA
- Microphone sensitivity (1Khz): 52-48dB
- Microphone Impedance: 2.2KΩ
- Microphone Frequency: 16-20Khz
- Microphone S/N ratio: 54dB
- Signal output indication
- Single channel signal output
- Outputs low level and the signal light when there is sound
Package Includes:-
1 x Voice Sound Detection Sensor Module

work as expected
These seem to work well, just check each one to verify at same setting of amplification if using in an array, only thing that is a little disappointing is the frailness of the mic leads — so I need to make a case for these to prevent breakage
