Abstract
Provided herein are a measurement device and an operation method thereof. The measurement device senses a distance variation between the measurement device and an object using a built-in proximity sensor and accordingly determines whether to turn on or turn off a track sensing module and an optical ranging module such that the measurement device provides intelligent selection to achieve energy saving without being interfered with by other sensors being turned on.
