Industrial sound level sensor.

So in this project we will use a normal electret condenser microphone with arduino and try measuring the sound or noise pollution level in db as close as possible to the actual value. It measures sound level to within 3 db along a single range from 55 to 110 db with no need to switch between ranges during an experiment. And up to 8 sensors can be. From the above information finally we can conclude that.

If you do not see what you are looking for ask an expert. Sound is detected via a microphone and fed into an lm393 op amp. When the sound level exceeds the setpoint an led on the module is illuminated and the output is sent low. Ultrasonic sensors use sound waves rather than light making them ideal for stable detection of uneven surfaces liquids clear objects and objects in dirty environments.

We will use a normal amplifier circuit to amplify the sound signals and feed it to arduino in which we will use regression method to calculate the sound signals in db. You can monitor classroom sound levels measure reverberation time and investigate sound insulation. It is able to analyze the surrounding ambient sound in the audible frequency spectrum for the human ear showing collected data in dba. The sound level setpoint is adjusted via an onboard potentiometer.

The ss1 ss2 and ss3 are a low cost way to input sound or noise information into a plc process control meter distributed control system dcs or other industrial control system. Sound level recognition not capable to obtain precise db value this article discusses an overview of the sound sensor. This information is essential in spaces with high levels of noise pollution or with restrictions on noise levels. Industrials traffic street ads alarms or works are the more common.

The sound level sensor is a weighted meaning it responds to sound loudness the same way the human ear does. Where to install the noise level sensors. There are different types of microphones which are known as sound sensors like dynamic condenser ribbon and carbon etc. The noise sensor is installed through a 3 8 9 5 mm hole in acoustic tile.

There are a wide variety of environmental noise sources. These sensors work well for applications that require precise measurements between stationary and moving objects. In the case of an open ceiling the noise level measurement meter can be attached to the structure. The sound detection sensor module for arduino detects whether the sound has exceeded a threshold value.

Typically one noise level measurement meter covers 1 000 sq. The sms sen sound level sensor measures the ambient noise level in a zone.
