A Comprehensive Smart Prevention System against Home Poisoning with Carbon Monoxide

ABSTRACT This paper presents a lifesaving smart mechatronic system that prevents poisoning from high concentrations of Carbon Monoxide. This proposed system provides a technical solution to attenuate the dangers of gas used for heating space and water. It relies on sensor nodes, actuator nodes, a main control node, and a corresponding smartphone application allowing emergency communication and remote monitoring of the heated rooms. Sensor nodes-composed of a gas sensor, a microcontroller, and an audiovisual alarm- as well as actuator nodes- which comprise a window actuator, a relay, and a microcontroller- are installed in rooms where heating is used. When the concentrations reach dangerous levels, the main control node, which consists of a microcontroller connected to a server, sends commands to the sensor nodes to turn an alarm on, and to the actuator node to automatically open the air vents and activate the fans to accelerate the renewal of air and decrease the gas concentration. Through a smartphone application, the suggested system notifies relative and/or emergency services. The paper presents the architecture and design of this scheme, details its components, and provides its cost analysis. Keywords: Carbon Monoxide, gas sensor, poisoning, smart system
