A carbon monoxide sensor with composite detection capabilities for carbon monoxide, hydrogen sulfide, and nitric oxide gases was developed using gas concentration detection technology based on composite electrochemical components to address the issue of crossinterference between exhaust gas and sulfur-containing gases from diesel vehicles and gasdetection by mining carbon monoxide sensors. The sensor gas detection module includes two parts: a carbon monoxide hydrogen sulfide dual gas detection module and a nitric oxide gas detection module. The module is composed of gasdetection components and signal detection circuits. An experiment was conducted to study the effects of hydrogen sulfide and nitric oxide gases on the detection results of carbon monoxide gas concentration. Through data analysis and linear fitting, a gas cross-interference compensation algorithm formula was obtained. The based on composite electrochemical elements has a measurement error of less than 5% in the mixed gas environment, meets the requirements of the AQ6205-2006 coal mine electrochemical carbon monoxide transducer, and can meet the technical requirements for the accurate detection of carbon monoxide gas of an underground rubber-tire truck transportation roadway.

Liquefied petroleum gas (LPG) is commonly used for heating, cooking, automotive power, and various other uses worldwide. LPG is a particularly flammable gas, and LPG leaks cause significant incidents. The cause may arise from improper installation to the use of faulty gas cylinders. Since LPG is an extremely volatile and flammable gas, a reliable safety system has been designed and developed using IoT (Internet of Things) capable of detecting gas leakage, turning on the emergency alarm, tracking the location, and sending alerts messages to users and nearest helpline number. The proposed model sort out into four modules, such as gas detection module (GDM) always detect the gas leakage to avoid unexpected incidents;Location detectionmodule (LDM) track the gas leakage location and pass the value to NM;Notification module (NM) is responsible for generating the message service to notify the nearest help center and user;In the case of a gas leak, the Alarm module (AM) is responsible for activating an emergency alarm. The result shows the system successfully performed. It can be noted that the proposed can be embedded with any environment, including home, office, ship, industry, etc.
