Audio Frequency Detector - Arduino Project Hub
https://create.arduino.cc/projecthub/lbf20012001/audio-frequency-detector-617856
This Arduino project displays the approximate frequency of the loudest sound detected by a sound detection module. For this project, the analog output from the sound module detector sends the analog audio signal detected to A0 of the Arduino Uno. The analog signal is sampled and quantized (digitized). A Fast Fourier Transform (FFT) is then performed on the …

This tutorial explains how to use the Audio Frequency Meter Library for Arduino Zero boards. The code uses a method of the library to measure the frequency of a signal connented to A0 and amplified through an electronic circuit, in order to get the frequency of a generic input signal. The range currently measured by the library spans from 60 to 1500 Hz and …

There's not a lot of information available from your link. The sensor has an amplifier that feeds into a fixed frequency tone detector that's manually set (via a potentiometer). The tone detector outputs a 5V logic signal ... +5V if the tone is present and 0V if the tone is not present. The Propeller uses 3.3V logic signals.

This sensor employs a microphone to provide input to buffer, peak detector and an amplifier. This sensor notices a sound, & processes an o/p voltage signal to a microcontroller. After that, it executes required processing. This sensor is capable to determine noise levels within DB’s or decibels at 3 kHz 6 kHz frequencies approximately wherever the human ear is sensitive.
