Abstract

Application of Prototype A tool for detecting noise based on NodeMCU is a prototype that can be used to detect sound noise and provide a warning if the sound exceeds the reasonable threshold that humans hear. The function of this system is to detect sound noise using the Analog Sound sensor V2. Then the data from the Analog Sound sensor V2 will be displayed in the form of a Led and if it has passed the threshold that humans hear, it will trigger turning on the buzzer as a warning and send automatically the decibel value, status and also if we want to check how much noise there is, we can type / telegram the sensor . Based on the data analysis carried out, Basically programming for building Prototype Tool for detecting noise based on NodeMCU using the C programming language with the help of Arduino IDE software and monitoring it using LED and Telegram. This research was made in order to facilitate controlling the noise in the environment.

Highlights

If the sound heard is more than 140 decibels, there can be damage to the eardrum and the organs in the eardrum. (Yoga Persada, Achmad Rizal, Muhammad Ramdhani 2012)
After the power is connected to the NodeMCU, it will be distributed throughout the equipment
To make a prototype tool for detecting noise in the research center and standardization of the NodeMCUbased Samarinda industry, which is needed, namely NodeMCU as the main hardware microcontroller and as a link to telegram, Analog sound sensor to capture sound voltage which is later forwarded to the LED, and buzzer as a marker and at the same warning indicator

Summary

INTRODUCTION

Sound is something that is very important in life, because it is with voice that a person can communicate with other people. Humans can hear sounds on a decibel scale (noise level) from 0 (very low), to 140 decibels (high and painful sounds). Human hearing can tolerate more than 80 decibels, provided the exposure time is considered. For eight hours a person works at 70 decibels. The noise level is 100 decibels, long working one hour. If a person works beyond the tolerable threshold, in the long term they will experience hearing loss
