In this project we will therefore create an IoT decibel meter to measure the sound at a specific location and record the value on a graph using IoT. Such a device is useful in hospitals and schools to track, monitor and take appropriate action on sound levels.
A sound level meter is used for acoustic measurements (sound moving through the air).
Sound level meters are commonly used in noise pollution studies to quantify different types of noise, particularly for industrial, environmental, mining and aircraft noise.
IoT Sound Meter Circuit Diagram:
Here we have to develop a code that picks up inputs from the sound sensor and maps this value in decibels. After comparing the volume, it should not only be printed on the 16 * 2 LCD display but also sent to the Blynk server.
The full operation of this project is also demonstrated at the link below. Hope you enjoyed the project and learned something useful if you have any questions, leave them in the comment section below.
