1. An inertial measurement unit (IMU) device comprising:
an IMU sensor;
a heat source;
a temperature sensor;
a controller configured to, in response to a temperature of the IMU sensor detected by the temperature sensor falling below a threshold temperature, control the heat source to generate heat; and
a heat conductive member configured to transfer heat from the heat source to the IMU sensor, wherein the heat conductive member includes an electrically insulating and thermally conductive material;
wherein the heat conductive member is filled between the heat source and the IMU sensor.
