Abstract
Provided are a sensor device and a sensing method using the same. The sensor device according to the present invention includes: a sensing voltage generating unit outputting different voltage values depending on an external environment; a pulse generating unit generating a pulse having a period which is proportional to an input voltage; a divider dividing an output of the pulse generating unit; and a counter unit measuring a length of an output pulse of the divider in a clock unit. As a result, the sensor device including an analog-digital converter (ADC) using a pulse width modulation technology is a miniature device and has high resolution.
