NOVELTY - Marsh gas pool set comprises: blade (1) above marsh gas tank (13); wind-powered generator (2); humidity sensor (9) in pool of marsh gas tank; upper part of biogas slurry (16) as marsh gas storage space (14), and is equipped with conductive wires (4), humidity sensor and circuit; display (20) in vicinity of tank; processor and receiving antenna (18) connected to controller (5) that is connected to inverter (6) that is connected to current divider (7), which is connected to humidity sensor, humidity sensor is connected with computer processor (10), and emitting antenna (11) is on processor.    USE - As marsh gas pool set having humidity sensor for monitoring humidity change in pool (claimed).    ADVANTAGE - The marsh gas pool set is provided with humidity sensor for monitoring humidity change in pool, as new energy internet application, where the marsh gas relative humidity is associated with yield of marsh gas tank, but marsh gas tank is tightly sealed. When marsh liquid is too dry, it is necessary to supply warm water at 20 degrees C to biogas slurry, so that slurry is diluted properly and methane bacteria can decompose organic matter more quickly. The method implies modern sensing technology i.e. electronic information technology, and provides humidity sensor in reservoir bag of marsh gas in marsh gas tank that can accurately sense reservoir bag of marsh gas by non-electric-quantity relative humidity information, which is then converted into electric signal, electric signal is inputted to computer processor and transmitting antenna installed on computer processor so that electric signal is transmitted as radio signal to air, receiving antenna receives marsh gas pool relative humidity as electrical signal, which after processing by computer processor is displayed as humidity value of the gas in tank on display. Thus in such humidity management, if humidity is found to be to low due to too little gas is found, humidity can be adjusted with humidifying water. The managing of relative humidity is not only good for improving yield of marsh gas tank, but is good for improving quality of methane.
