Abstract

Provided is a physical quantity detection device capable of reducing current consumption by controlling an energization method even during a ground contact period. A physical quantity detection device 2 according to the present invention extracts a step-in peak value 43 of strain occurring at a time Pa of step-in when a strain detection region 10 a of a tire 10 comes into ground contact with a road surface 30 and an intermediate time point peak value 42 of strain occurring at an intermediate time point Pb between the time of step-in and a time of kick-out when the strain detection region of the tire is separated from the road surface, calculates a cycle in which the step-in peak value and the intermediate time point peak value occur subsequently, based on a time difference t from the step-in peak value to the intermediate time point peak value or an inclination of a change in strain, and energizes a strain detection unit 3 in accordance with the cycle.
