ZITRADES High Sensibility microphone sensor module fit for KY-037 ARDUINO with 2 output by ZITRADES

I bought this to test out the microphone capabilities of my Arduino Uno board. It comes in a small sealed package with ZERO documentation. However, the board is labeled and it has 4 pins; Analog Out, Power, Ground, and Digital Out. I connected the Power to 5V on the Arduino, Ground to Ground, and Analog to Analog 0. I opened up the Serial Monitor and I could see it picking up sound. If I clapped or shouted into the mic, the output numbers would raise dramatically.I had to google some test code for the microphone (I'm a newbie to all this,) but in under 10 minutes I had found a very simple code that allowed me to set a threshold level for the microphone which would turn LED's on/off once the threshold was passed. Hooked up two red LED's and I had them turning on when I would speak; turning off when there was silence!The microphone will work without a pre-amp; but it does seem like the detection is pretty low without it. I can definitely make the output jump by shouting into close; but I bet with a small pre-amp coupled with it you could make it pick up quite a bit.Would recommend this for testing; not sure how this would hold up in a real world project. Definitely works; google examples of the code (I found the working code on the Arduino dot cc website.)

WITH ANY EFFORT WHATSOEVER THIS WILL WORKI bought this to make an audio-responsive LED setup. It comes with no documentation, but just reading the board tells it all: power to +, ground to G, analog output from A0, digital from D0.Sensitivity isn't great, but it works as a basic sound sensor. I'll be trying more advanced analysis of incoming signal later; math ability is currently a constraining factor.My sketch consistently gets the LEDs to blink along with music. The mic is most responsive to the bass, so I put it near a sub. Play with the threshold value as needed. Sorry it's a bit messy, I'm working on a few other aspects currently so some things are just sitting there.Example video: https://www.youtube.com/watch?v=4rlYRWBTKIM&list=UUOY0wkoxYrjGluAAY-eQRLQ (notice ambient noise is blocked out with proper threshold value and mic placement)Sketch:// initialize LEDsint ledR = 3; // redint ledY = 5; // yellowint ledG = 6; // greenint leds[3] = {ledR, ledY, ledG}; // led array// setupvoid setup() { // initialize serial communication at 9600 bits per second: Serial.begin(9600); // set LED pins as output for (int k = 0; k < sizeof(leds) - 1; k++) { pinMode(leds[k], OUTPUT); }} //setupint i = 0; // indicates first iteration of main loopint thresh = 30; // dummy valueint duration = 100; // default duration of LED blink// mainvoid loop() { // read analog mic input int micRawSignal = analogRead(A0); if (micRawSignal > thresh) { Serial.println(micRawSignal); } // check if value exceeds threshold if (micRawSignal > thresh) { // turn on LED analogWrite(ledR, 250); analogWrite(ledY, 250); analogWrite(ledG, 250); delay(duration); } else if (micRawSignal < thresh) { // turn off LED analogWrite(ledR, 0); analogWrite(ledY, 0); analogWrite(ledG, 0); } // else} // main

Does NOT work. HOoked it up, analog output stayed at 1.7V and never moved no matter how loud I yelled at it. It didn't want to sense my loud anger that I have to demo something tomorrow. I should have never bought from a company that idolizes Thomas Edison. I wish I checked their website before I bought.

Bad ! Not sensitive at all. Both digital and analog mode are waste. Always give you same value. Basically insensitive to sound. It is sensitive to vibrations. If you tap the microphone then it will give some readings but that was not what is wanted. I wanted to use it for a clap switch, not the thing for it.Update: Company sent me a new one. This one works well but still not perfect for my application. Anyways worth a shot

There was not enough description on this product. It is built to detect loud noises like breaking windows or gunshots. and descriptions on how it works are hard to find. if you want a more sensitive microphone get the one with the small silver mic on the end and a ribbon cable to conect it to your solderless breadboard.

Analog output values are not sensitive.Pot is used to set threshold for DO. This basically only useful as a volume threshold sensor. Analog values are worthless.Now to try http://www.amazon.com/Arduino-compatible-Mini-Sound-Sensor/dp/B00AF2GB1U/

Worked well. Not much more I can say on it.

Terrible! When it was working it could barely read the sound, and it broke after second use. Save yourself some time and spend some extra money on getting a better microphone.
