Laser level with temperature control device and temperature control method thereof

A laser level comprising:

• a level adjustment device comprising:
• a tilt sensor, which generates an output signal corresponding to a measurement,
• a processor unit, which receives the output signal from the tilt sensor and proceeds with calculation on the output signal, and
• an actuator, which is controlled by the processor unit based on the calculation to a horizontal position of the tilt sensor;
• a temperature control device comprising:
• a thermal insulation chamber, in which the tilt sensor is received,
• wherein the temperature control device detects an external temperature outside the thermal insulation chamber and generates a corresponding first temperature signal, and
• wherein the temperature control device detects an internal temperature inside the thermal insulation chamber and generates a corresponding second temperature signal, and
• a control unit, which receives the first and second temperature signals and, based on the temperature signals, controls a temperature adjustment unit to adjust the internal temperature inside the thermal insulation chamber;
• and
• a laser device movable with the movement of the tilt sensor of the level adjustment device to correspondingly adjust horizontal position.
