摘要:An ultrasonic nsor 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 ction configured to detect an ambient humidity of the transmitting and receiving devices and a threshold adjustment ction configured to calculate, bad 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 nsor and the object. The threshold adjustment ction reduces the first threshold, when the output voltage corresponding to the calculated sound pressure is less than a cond threshold that is greater the first threshold.
