A seem degree meter is applied for acoustic (sound that travels through the air) measurements. The most effective sort of microphone for seem stage meters is the condenser microphone, which combines precision with security and reliability.

Decibel meter is typically made use of in noise pollution studies for the quantification of diverse forms of sound, specially for industrial, environmental, mining, and plane sound.

In this IoT task, we will make Decibel Meter working with ESP8266 & Seem Sensor. This DIY challenge is really simple and can be built at house for monitoring loudness in dB. We will use Nodemcu ESP8266, Audio Module & Screen both 16×2 Lcd Show or OLED Display screen. The Seem Sensor will detect the audio and change it into an analog voltage which is go through by Nodemcu ESP8266. The Nodemcu connects to wifi and uploads the info to Thingspeak Server.
