In today’s store-houses the ripening of fruit is controlled by managing the ethylene concentration in the ambient atmosphere. Precise and continuous ethylene monitoring is very advantageous since low ethylene concentrations are produced by the fruit itself and are indicative of its ripeness, and on other occasions, ethylene is externally added when ripeness or degreening of the product must be promoted.

Information about the environment is essential for the survival of every living being, since it determines the way to react with respect to external inputs. In the case of humans, this information is collected through the five senses; sight, hearing, touch, smell and taste. Sight, hearing and smell senses are considered specially interesting because of their ability to get external information without direct interaction with the sources. Sight is probably the most developed sense in humans, followed closely by hearing.
