Document Type and Number:
Japanese Patent JP6544284
Kind Code:
B2
Abstract:
A sensing device (10), provided with: a piezoelectric element (20) for outputting received ultrasonic waves as an electrical signal; a signal processing unit (40) for acquiring the electrical signal outputted from the piezoelectric element (20), the signal processing unit (40) being connected to the piezoelectric element (20); a switching unit (50) for switching between a state of electrical connection and a state of disconnection of the piezoelectric element (20) and the signal processing unit (40); and a determination unit (62) for sensing electrical noise on the basis of an acquired electrical signal when the signal processing unit (40) acquires an electrical signal in a case in which the switching unit (50) is in the disconnection state.
