Gas leaks, particularly of gases like carbon monoxide, methane, and liquefied petroleum gas (LPG), pose significant dangers due to their flammability and toxicity. LPG, widely used in residential and industrial settings, is especially hazardous because it is colorless, odorless, and highly flammable, making undetected leaks an explosion risk. To mitigate these dangers, modern gas detection systems employ sensors, microcontrollers, and real-time monitoring to quickly identify dangerous gas levels. This study introduces an IoT-based system designed for comprehensive environmental monitoring, with a focus on detecting LPG and butane leaks. Using sensors like the MQ6 for gas detection, MQ135 for air quality, and DHT11 for temperature and humidity, the system, managed by an Arduino Mega, collects data and sends these to the ThingSpeak platform for analysis and visualization. In cases of elevated gas levels, it triggers an alarm and notifies the user through IFTTT. Additionally, the system includes a microphone and a CNN model for analyzing audio data, enabling a thorough environmental assessment by identifying specific sounds related to ongoing activities, reaching an accuracy of 96%.<\/jats:p>","DOI":"10.3390\/computers14020033","type":"journal-article","created":{"date-parts":[[2025,1,22]],"date-time":"2025-01-22T03:40:17Z","timestamp":1737517217000},"page":"33","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Use of IoT with Deep Learning for Classification of Environment Sounds and Detection of Gases"],"prefix":"10.3390","volume":"14","author":[{"given":"Priya","family":"Mishra","sequence":"first","affiliation":[{"name":"Department of Communication Engineering, School of Electronics Engineering, Vellore Institute of Technology, Vellore 632014, TN, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2602-0731","authenticated-orcid":false,"given":"Naveen","family":"Mishra","sequence":"additional","affiliation":[{"name":"Department of Communication Engineering, School of Electronics Engineering, Vellore Institute of Technology, Vellore 632014, TN, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5450-4034","authenticated-orcid":false,"given":"Dilip Kumar","family":"Choudhary","sequence":"additional","affiliation":[{"name":"Department of Communication Engineering, School of Electronics Engineering, Vellore Institute of Technology, Vellore 632014, TN, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8319-1583","authenticated-orcid":false,"given":"Prakash","family":"Pareek","sequence":"additional","affiliation":[{"name":"Electronics and Communication Engineering, Vishnu Institute of Technology, Bhimavaram 534202, AP, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8872-5721","authenticated-orcid":false,"given":"Manuel J.
