Beschreibung
Zusammenfassung:	The invention provides a differential pressure sensing module and a mine ventilation monitoring system, and the module comprises a first sensing module which is used for generating deformation according to the differential pressure between a first end and a second end, and outputting a first differential pressure value according to the deformation; the second sensing module is used for outputting a second differential pressure value according to the temperature difference between the first end and the second end; and the processing module is used for obtaining an actual differential pressure value between the first area and the second area according to the first differential pressure value and the second differential pressure value. According to the differential pressure sensing module and the mine ventilation monitoring system disclosed by the invention, the processing module can obtain the actual differential pressure value between the first area and the second area according to the first differential press
