The invention belongs to the technical field of inertial sensors, and discloses a temperature control type magnetic liquid acceleration sensor. The temperature control type magnetic liquid acceleration sensor solves the problem that when an existing magnetic liquid acceleration sensor is used and the temperature is excessively high or low, the physical property of magnetic liquid changes, so that the normal work of the sensor is influenced. The sensor is composed of an outer shell, an inner shell, an air inlet port, an air outlet port, a temperature sensor, an end cover, a screw, a cylindrical permanent magnet, the magnetic liquid, a sensor outgoing line and a rubber plug. When the temperature sensor detects that the temperature is excessively low or high, the sensor outgoing line sends feedback signals, the temperature sensor receives the signals and then controls an external air breather to inject protection gas into a cavity formed by the outer shell and the inner shell for heating or cooling the inner she
