Sistema de control y monitoreo para electroválvulas de gas de uso doméstico.

Abstract

A visualization, monitoring and control system for domestic gas solenoid valves was developed. The system has the implementation of two carbon monoxide and methane gas sensors, based on the reading made by the Mbed Nucleo 446RE microcontroller of the sensors, a control process is carried out for the gas solenoid valve that will allow the quantity or gas concentration allowed in the area under safety standards, that is, once the sensors detect an over concentration of gas, the system will disable the solenoid valve and activate the danger indicators, which in this case has an alarm system It will sound, together with three indicator lights and an LCD screen that will allow the user to identify the danger and the current state of the gas concentration. The system has a serial communication protocol with a Raspberry pi development microprocessor that allows, through a server hosted on the card, communication via internet between the control and monitoring system together with a graphical user interface developed so that the person is informed from anywhere with internet access about the current status of the valve and whether the gas concentration in the area is within the stipulated safety framework.
