The present invention relates to a method for measuring positions by correcting temperatures in a precision device for measuring positions using a magnetoresistive sensor and a magnetoresistive sensor module mounted on the precision device to measure positions using the same. The present invention provides a method for measuring the positions of a moving unit of a precision device to be corrected according to temperatures comprises a step of setting a magnetoresistance reference value (step 1); a step of storing a measured magnetoresistance reference value according to measured temperature changes of the precision device (step 2); a step of setting and storing a magnetoresistance value for different temperatures (step 3); a step of repeatedly setting and storing magnetoresistance values by repeating the step 2 and 3 when temperature changes are detected while the precision device operates during the step 2 and 3 (step 4); and a step of measuring the position of the moving unit (step 5). Also, the present invention provides a temperature correctable magnetoresistive sensor module comprising a magnetoresistive sensor (100), a variable amplification amplifier module (300), an A/D conversion unit (400), a microprocessor (500), a controller (510), a memory storage device (600), and a temperature sensor (700). |
