Hey sorry for the late reply, the internet was down. The problem is now solved, tested it the way you suggested and found that it was the board that wasn't working. Receiving partial information does not help me help you and wastes my time. Jul 10, 2011, 12:02 am. For this, I have designed a couple of circuit where in the first circuit I will just interface the Sound Sensor with Arduino and detect the sound with the help of an LED. This is the code you indicate does not run. To answer the question it was purchased built. Being new to electronics, is there something wrong with the sensor or is it something I'm doing? I will document it soon, but I just keep finding new effects to code into it! You can tell your board what to do by sending a set of instructions to the microcontroller on the board. It gives a measurement of how loud a sound is. Damit wird die vom Mikrofon erzeugte Spannung mit dem Operationsverstärker verstärkt und … I confess the diode I used was not the same (1N4004). Have a data sheet for sensor or link to grab it? I'm current working on a project with an RGB LED, hoping to change the colour according to how loud the sound is. If a baby cries too loud it sounds the “alarm” in the parents’ baby intercom so they hear the baby cry. If the amp is bad I guess I'll have to get another sound sensor, down side is the long wait. When connected to a speaker there is just a constant hum/ noise, it doesn't change in response to other noises. Rookie101 Guest; Problem with Sound sensor. Great. I won't be able to get another one soon. I'm working on another one right now that drives a 7 foot LED light bar to audio output from a TV. You can open the Serial Monitor by going to Tools > Serial Monitor or pressing the magnifying glass-button in the Arduino software window. would a regular mic work with the circuit you provided? Coming to the second circuit, I will control a relay with the help of sound (snap of fingers). Sound Sensor Working and Its Applications Nowadays, a lot of security events are initiated due to some sort of sound which includes gunshots, aggressive behavior, breaking the glass. In the figure below you can see the most common used with the Arduino. As the project is about interfacing a Sound Sensor with Arduino, let us see how its done. Händeklatschen oder Klopfen erkennen und darauf reagieren. Pages:  Topic: Problem with Sound sensor (Read 9525 times) previous topic - next topic. I have arduino project - House automation. We measure the sound level in decibels (dB). I am 100% it is connected properly ( I had the same step up when I got the sensor to test it, clap my hands and the LED blinks). To get an easier start you can use a shield... http://www.analog.com/en/rfif-components/detectors/ad8307/products/product.html, http://bliptronics.com/item.aspx?ItemID=116. > Using Arduino > Sensors > Problem with Sound sensor; Print. I've even tried it with a simple sketch to make sure my code was not the problem. This post shows how to use the microphone sound sensor with the Arduino board. Was the sound sensor issue resolved? I've connected a capacitor in series to the analog input, only change is that it now reads 699 constantly instead of 705, and still does not react to sound. Mit einem Sound Sensor Modul für den Arduino kann man ganz einfach laute Geräusche wie z.B. Die gängigen Schallsensoren aus den verschiedenen Arduino Starter Kits basieren meistens auf einem Operationsverstärker wie dem IC LM393. Does the Sound sensor work? There are a wide variety of these sensors. I'm using a DFRobot sound sensor, and the … Especially the article regarding envelope follower circuits, that put things in a better perspective. I have the usual usb that I normally use as well as a connector to a 9V battery, both pretty much have the same results, except that the battery gives a reading of 1023 while the usb gives one of 705 and both values remain constant. If you really want to go crazy with LED(s) and audio, try out a MSGEQ7 - Seven Band Graphic Equalizer Display Filter. Thanks for the help guys! I've just tried using my vibration sensor the same way and it works perfectly. Sound sensors also tell you the sound “level.” The best known example of a sensor that can measure the sound level is the decibel meter, but a baby alarm can also register the sound level. The microphone sound sensor, as the name says, detects sound. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. The Microphone Sound Sensor. If not, I'd leave the whole code and comment out all the code but the sound sensor and one other thing do, such as the servo thing do. That was one of the first problems i read about and checked out while googling. I'm using a DFRobot sound sensor, and the problem is when ever I look at the Serial monitor I get the same value 705, sometimes 704 or 706. 1st code: It does print "Boo" every 1000mS. But cameras with inbuilt sound exposure facilities can add huge value to the security system. So what happens if you change the code to, Sound sensor not working in whole project, Topic: Sound sensor not working in whole project, https://github.com/septillion-git/FadeLed, Re: Sound sensor not working in whole project, Quote from: ajmemeni on Jul 16, 2019, 07:29 pm, Quote from: Idahowalker on Jul 16, 2019, 07:43 pm, Quote from: ajmemeni on Jul 16, 2019, 10:14 pm. If the sound does not sense very well, try changing the threshold value or changing the sensor sensitivity by rotating the potentiometer. I'm current working on a project with an RGB LED, hoping to change the colour according to how loud the sound is. I meant getting one from another appliance. I am going to look in to making my own at a later stage because the DFRobot ones are all I have access to. But thanks, I will give the test a try. I have used the MSGEQ7 chip by itself on several projects with great success. Purchased a new one which has just arrived and have it set up exactly the same way, running the same code and everything is working perfectly. Go Down.
