IoT-Enabled Smart Benzene Gas Detection System in Petrol Pumps for Smart City Applications

This paper discusses the role of smart sensors in improving safety at petrol pumps by detecting benzene leakage. Benzene is a dangerous chemical that can cause cancer and health issues, and petrol stations are a major source of benzene emissions. The paper emphasizes the importance of real-time monitoring and detection of benzene leaks at petrol pumps, proposing a system using an Arduino Uno microcontroller and a GSM SIM 800L module for IoT communication. The system utilizes an MQ-135 gas sensor to detect benzene concentration and sends SMS alerts to a designated phone number if a leak is detected. The study concludes that implementing such systems in smart cities can significantly enhance petrol pump safety and reduce the risk of benzene exposure.
