Abstract: A sensing device is provided. The sensing device includes a processing circuit and a multi-sensor integrated single chip. The multi-sensor integrated single chip includes a substrate and a temperature sensor, a pressure sensor, and an environmental sensor disposed on the substrate. The temperature sensor senses temperature. The pressure sensor senses pressure. The environmental sensor senses an environmental state. The processing circuit obtains a first sensed temperature value from the temperature sensor when the environmental sensor does not operate, and it obtains a second sensed temperature value from the temperature sensor when the environmental sensor operates. The processing circuit obtains a sensed pressure value from the pressure sensor. The processing circuit obtains at least one temperature calibration reference of the pressure sensor according to the first and second sensed temperature values and calibrates the sensed pressure value according to the temperature calibration reference.

Abstract: A sensing device is provided. The sensing device includes a plurality of infrared thermosensitive elements and a plurality of resistor-capacitor (RC) oscillators. The plurality of infrared thermosensitive elements are arranged in an array. Each of the plurality of infrared thermosensitive elements has a resistance value which changes with a temperature of the infrared thermosensitive element by absorbing infrared radiation and generates a sensing voltage corresponding to the resistance value. The plurality of RC oscillators are coupled to the plurality of infrared thermosensitive elements to receive the corresponding sensing values, respectively. Each of the plurality of RC oscillators generates a digital sensing signal according to the corresponding sensing value to indicate the temperature of the corresponding infrared thermosensitive element. Each of the plurality of RC oscillators is disposed under the corresponding infrared thermosensitive element.

Abstract: A resistive gas sensor is provided. The resistive gas sensor includes a sensing circuit and a determination circuit. The sensing circuit senses a gas to generate a detection signal. The determination circuit performs a frequency-division operation on the detection signal by a frequency-division parameter to generate a frequency-division signal, counts a half of a period of the frequency-division signal to generate a half-period count value, and determines concentration of the gas according to the half-period count value. The determination circuit determines the frequency-division parameter according to the half-period count value.
