Among the technologies for noninvasive clinical diagnosis, the metal oxide semiconductor gas sensor technology has recently attracted considerable attention because of its advantages such as simplicity, miniaturization possibility, low power, and low cost production. The electrical property of this gas sensor is proportional to the moisture adsorption for the same microstructure sensing material and at the same surface temperature, which implies that it is also proportional to that at the time when no power is supplied. In this study, the initial behavior of the metal oxide semiconductor sensor was measured and analyzed in three stages according to the time when no power was supplied to the sensor. The analysis revealed that the initial peak voltage, stabilization time, load voltage, and sensor resistance of the initial behavior stage had a significant relationship with the sensor’s no-power time, therefore; the initial behavior characteristics of the gas sensor according to the usage pattern of the portable device were visualized. In addition, a load-resistive active control algorithm is developed as a method to obtain the maximum sensitivity independent of the portable device’s usage pattern for various concentrations of the target gas.
