The Development of a Portable Gas Leak Detection System Using IoT

There are high-risk issues involved in industries which use hazardous gases in large quantities
for their various processes. People may not identify or monitor the leakage of these gases on a
regular basis before it goes out of hand. There is a need for sensors to continuously monitor the
leakages and alert the users on the possible hazard. This project gives the solution to reduce
the risk factors in isolated areas having large gas installations by detecting and displaying the
leakages continuously. Leakage of gas can occur at multiple points in the same installation.
Hence, multiple sensors are implanted as close as possible to the potential leak site and able to
detect the leakage and transmit the signals to the base station located far away. Using
microcontroller, multiple sensor values are received and processed. The processed data is
encoded in Wireless Module and transmitted to the base via the Internet of Things connection
where another microcontroller decodes it and shows the respective sensor status. The system
also gives an audio and visual warning when leakages are detected and as the time taken to
detect is very low due to high-speed processing, the leakage situations are brought under
control with minimal or no damage. This project gives an economical and efficient method to
reduce leakage risk by using latest IoT technologies and monitoring anywhere on the web.
