Detección de gases peligrosos con sensores MQ - 330ohms

· Los gases peligrosos difícilmente pueden detectarse a simple vista; el gas butano o el monóxido de carbono son invisibles al ojo humano. Algunos tienen un olor perceptible, pero sólo hasta que hay una cantidad suficiente. Para detectar pequeñas cantidades, como en el comienzo de fugas o en entornos controlados, podemos usar un sensor de gas. Los sensores de gas de la serie MQ es la …
