An IoT noise and air quality observation system are a device that is used to detect a noisy sound. Besides that, it also will detect any leak gas. This is a project that used a combination of electronic components and software. It will send the information on the Blink application if there is any leak gas or a noisy sound on that area. It is essential to use it in dangerous places like hospitals. In this project, Arduino UNO R3, NodeMCU, gas sensor, sound sensor, and resistor are the components that had been used. From this project, it can help a company or a place from facing dangerous problems such as fire, explosion and disturbances that can disturb the order of a place.
