The present invention relates to a portable device for detecting toxic gases in confined environments. Said device consists of a box with a sensor that detects vapors of organic substances, such as acetone, chloroform, methanol, ethanol, their mixtures, ammonia gases, and carbon dioxide flue gas. The sensing component is a sophisticated graphene carbon nanomaterial coated with a cross-linked polymer. Also, the device activates two alarms: an LED-type bulb and a vibrator when the sensor assembled inside the box meets a toxic atmosphere. El Aparato portátil detector de gases tóxicos en entornos confinados, es uno constituido por una caja constituida por varios componentes y uno de ellos es un sensor que detecta vapores de sustancias orgánicas como acetona, cloroformo, metanol, etanol, sus mezclas, gases de amoniaco y gas de combustión bióxido de carbono. El componente sensor es un sofisticado nanomaterial de carbono grafénico recubierto de polímero entrecruzado. El aparato activa dos alarmas: un foco tipo LED y un vibrador, cuando el sensor ensamblado dentro de la caja entra en contacto con una atmósfera tóxica.
