The invention relates to an optimized device for the regulation and measurement of the oxygen content or content of any other gas in composting platforms or platforms for the treatment of waste. The device comprises at least one offset cabinet (4) comprising one or several gas measurement probes (5), and in particular, at least one probe for the measurement of oxygen or CO2; a gas suction pump (6), a programmable controller (9) which can comprise electrovalves which are integrated inside said programmable controller; an air supply pipe (11) which links each of the electrovalves (8) to a tube for the collection of gas (10) which can be placed in a pile or piles of waste or compost (14). According to the invention, the collection tube corresponds to one single electrovalve supply pipe, comprising an air suction basket (15); the electrovalves which are coupled to the pump succesively enable the suction of air and gases contained in the air for each tube and ensure that the air and gases are transmitted to a measuring probe or probes (5).
