Abstract: A thermal image-based temperature measurement calibration method applicable to a thermal image device is provided. The method includes a capturing stage, a processing stage and a calibration stage. During the capturing stage, the thermal image device captures a monitored environment to obtain a measured thermal image. During the processing stage, a processor processes on the measured thermal image to obtain a target information, wherein the target information corresponds to a target in the monitored environment, and the target information includes a target image block and a target measured temperature corresponding to the target image block. During the calibration stage, the processor obtains a distance compensation value according to a pixel number of the target image block, and the processor performs a calibration operation to the target measured temperature at least according to the distance compensation value to obtain a calibrated temperature value corresponding to the target.

Abstract: A water quality detection device including a detection tank, a sensor, the cleaner and a processor is provided. The sensor is disposed on the detection tank and is configured to sense a to-be-detected liquid within the detection tank. The cleaner is configured to clean the sensor. The processor is electrically connected to the sensor and the cleaner and is configured to: execute an initialization procedure, which includes driving the sensor to sense the to-be-detected liquid to obtain a number of initial sensing values and calculating a threshold value according to the initial sensing values; drive the sensor to sense the to-be-detected liquid to obtain a sensing value of the to-be-detected liquid, and determine whether the sensing value of the to-be-detected liquid reaches the threshold value; drive the cleaner to operate when the sensing value of the to-be-detected liquid reaches the threshold value.

Abstract: A physiological signal measuring method and a physiological signal measuring device are provided. The physiological signal measuring method includes the following steps: A first inputting signal having a first frequency, a second inputting signal having a second frequency and a third inputting signal having a third frequency are respectively inputted to at least two electrode sheets attached on a skin. A first impedance value corresponding to the first inputting signal, a second impedance value corresponding to the second inputting signal and a third impedance value corresponding to the third inputting signal are respectively measured. An interference impedance between the electrode sheets and the skin is obtained according to the first frequency, the second frequency, the third frequency, the first impedance value, the second impedance value and the third impedance value. A measured physiological signal is corrected according to the interference impedance to obtain a corrected physiological signal.
