Industrial Plant Environment Surveillance and Safety Assurance System Based on IoT

Most of the accidents like blasts, fire-breakouts in industries occur due to the industrial high temperature and toxic gas leaks. This does significant harm to the machinery, human life, and the environment. At the moment, the people are using traditional the gas-leak detectors which only generate on-site alarms. So, this project proposes industrial environment surveillance and a safety assurance system through which the real-time monitoring of the industrial environment is possible through a cloud storage server (such as Google Drive) and the system is also capable to send the warning to the client or person assigned for supervision through SMS. This low-cost project includes Arduino Mega R3 as an MCU (Microcontroller Unit), DHT11 sensor for temperature and humidity sensing; MQ2, MQ7, and MQ135 gas sensors, ESP-8266 as a WLAN communication module to connect the system with the cloud and GSM module to send SMS depending on the pre-defined threshold to the specified person.
