Disclosed is the sensor module, including a housing having a connection path connected to a channel on which a fluid flows; a sensor disposed inside the housing so as to be communicated with the connection path, and measuring information about the fluid introduced from the connection path; and an overpressure protection means disposed at the connection path, and selectively blocking the connection path according to a pressure applied from the fluid so as to prevent the transfer of a pressure greater than a reference pressure to the sensor, the circulation system having the same, and the method for assembling the sensor module. It can prevent the transfer of an excessive pressure of the fluid to the sensor, thereby preventing the sensor from being damaged by the overpressure.
