摘要
Calibration of a sensing device is provided. The sensing device includes a sensor configured to sense a condition. In the sensing device, a voltage-dividing resistance and a reference voltage of an analog-to-digital converter are set to configure a quantization range of the analog-to-digital converter given characteristics of the sensor. During calibration, a binary search is performed between lower and upper limits of the voltage-dividing resistance, which is a variable resistance, to find the resistance of the voltage-dividing resistance at which the sensing device is operated.
