    摘要: An ultrasonic sensor includes a transmitting device, a receiving device, and a circuit device. The circuit device determines that the receiving device receives an ultrasonic wave reflected from an object, when an output voltage of the receiving device is equal to or greater than a first threshold. The circuit device includes a humidity detection section configured to detect an ambient humidity of the transmitting and receiving devices and a threshold adjustment section configured to calculate, based on the detected ambient humidity, a sound pressure of the ultrasonic wave that is received by the receiving device after propagating over a round-trip distance between the ultrasonic sensor and the object. The threshold adjustment section reduces the first threshold, when the output voltage corresponding to the calculated sound pressure is less than a second threshold that is greater the first threshold.

    摘要: In a direction detecting device, a transmitting wave generator encodes a transmitting signal with a code having a high autocorrelation so as to generate a transmitting wave. A transmitter transmits the transmitting wave and a plurality of receiver elements receives a reflected wave reflected by an object. A direction calculating unit calculates a direction of the object based on a phase difference between a correlation value calculated based on the reflected wave received by one of the receiver elements and a correlation value calculated based on the reflected wave received by another one of the receiver elements, a distance between the one of the receiver elements and the another one of the receiver elements, and a wavelength of the transmitting wave.

    摘要: A capacitive humidity sensor includes a semiconductor substrate, a protective layer and a humidity sensitive section including a pair of comb electrodes and a humidity sensitive layer having a dielectric constant, which changes in accordance with humidity. The comb electrodes are disposed on one surface of the semiconductor substrate through the protective layer to face each other with a predetermined gap. An interface between the protective layer and the humidity sensitive layer is planarized so that the sensor prevents a hysteresis in a variation of capacitance. For example, a surface of the protective layer can be made flat by polishing.
