  • Water content sensor and road surface state detection device
    Patent number: 11480520
    Abstract: A water content sensor includes: a light emitter that emits detection light having a first wavelength band and reference light a second wavelength band toward a road surface; a first light receiver that converts the detection light reflected by the road surface to a first electric signal; a second light receiver that converts the reference light reflected by the road surface to a second electric signal; and a computation processor that detects the amount of water based on a signal ratio between the first electric signal and the second electric signal. The computation processor detects the amount of water based on the signal ratio obtained when the signal intensity of at least one of the first electric signal and the second electric signal is within a predetermined range defined relative to a reference value.
