A laser level with temperature control device () and the temperature control method thereof are disclosed. The temperature control device includes a thermal insulation chamber (), a thermoelectric cooler (), a control unit (), and first and second temperature sensors (). The second temperature sensor is received in the thermal insulation chamber together with a tilt sensor (). The control unit controls operation of the thermoelectric cooler according to the external and internal temperature signals respectively output by the first and second temperature sensors, so as to adjust the internal temperature inside the thermal insulation chamber to be a calibration temperature point close to the external temperature. Accordingly, the temperature drift problem can be addressed, and the working temperature of the tilt sensor can be maintained in a stable range. Further, the acceptable ambient temperature range within which the tilt sensor works can be expanded.

Laser level with temperature control device and temperature control method thereof

A laser level includes a level-adjusting device and a laser transmitter device mounted on the level-adjusting device. The level-adjusting device includes a horizontal flat board movable by a plurality of motor modules to a desired condition, a cross rotatable circle including an outer circle rotatable about a first rotation axis and a concentric inner circle rotatable about a second rotation axis perpendicular to the first rotation axis, and a connecting post connecting the horizontal flat board to the cross rotatable circle and supporting the laser transmitter thereon.

Laser level with improved leveling adjustability

The present invention discloses a laser tilt apparatus and the method thereof. The present invention comprises an input device, a tilt sensor, a motor, a microcontroller unit, and at least a laser module. The input device is used to input a tilt value. The tilt sensor supplies a tilt signal to represent the levelness of the laser tilt apparatus. The motor, electrically connected to the tilt sensor, adjusts the levelness of the laser tilt apparatus. The microcontroller unit samples the tilt signal to judge the levelness of the laser tilt apparatus. When leveling, the microcontroller unit drives the motor to adjust the tilt apparatus until the tilt signal matches the tilt value. After adjusting, the power supplied to the tilt sensor and the motor is suspended. The laser module is used to transmit laser light.
