DETECTION DEVICE
First Claim
1. A current output-type detection device that changes an amount of current consumption of the device itself in response to a detection result, the detection device comprising:
- a sensor circuit that detects a physical quantity to be detected;
a sensor signal processing circuit that outputs a detection signal upon receiving a signal of a detection result of the sensor circuit; and
a control circuit that outputs control signals to the sensor circuit and the sensor signal processing circuit and receives the detection signal from the sensor signal processing circuit,wherein the sensor circuit and the sensor signal processing circuit operate intermittently by the control signals.

Abstract
Disclosed is a current output-type detection device capable of reducing an amount of power consumption without sacrificing detection accuracy. The detection device includes: a sensor circuit; a sensor signal processing circuit that outputs a detection signal upon receiving a signal of a detection result of the sensor circuit; and a control circuit that outputs control signals to the sensor circuit and the sensor signal processing circuit and receives the detection signal from the sensor signal processing circuit, configured in that the sensor circuit and the sensor signal processing circuit operate intermittently by the control signals from the control circuit.
