Over the years, there have been reported incidences of deaths in the oil and gas industry due to gas explosions. This is due to the delay in the detection of leakages from oil and gas pipelines, especially the flammable gases. This work aims at developing an IoT-based system to detect the presence of methane (a component of natural gas), LPG, CO and temperature levels, to mimic gas leakages in an oil and gas field pipeline; as well as a valve control system to remotely shut off the gas supply in case of detected leakages. MQ2, MQ5 and MQ7 gas sensors were used. The temperature sensor used to detect when there is an explosion is the DS18B20 sensor. Arduino Nano and ESP8266 Microcontrollers were used to process and transmit the received data over the internet, respectively. The system was able to send danger alerts through a buzzer on-site and email to the remote supervisor. It was also able to trigger the shutting of the valve to cut off the supply to the leaking pipe.
