  • Publication number: 20240094075
    Abstract: A sensor device includes multiple sensors, a controller, and multiple communication paths. Each of the sensors includes a sensor element and a sensor-side communication circuit. The sensor element detects a change in a physical quantity. The sensor-side communication circuit transmits a signal having a response signal according to a detected value of the sensor element, in response to a request signal transmitted by a controller. The controller includes a controller-side communication circuit and an arithmetic processing unit. The controller-side communication circuit transmits the request signal and receives the response signal. The arithmetic processing units calculates detection data according to the response signal. The communication paths respectively connect the sensors to the controller. The arithmetic processing unit calculates detection data by adopting respective response signals in parallel acquired from the sensors.
