description The invention relates to a cascade double-ring resonant cavity sensor based on temperature control, and the sensor comprises a cascade double-ring resonant cavity sensor which is connected with a light source through an input waveguide, and is connected with a detector through an output waveguide. The waveguide of the reference ring and the waveguide of the sensing ring of the cascade double-ring resonant cavity sensor are connected through a conical waveguide, and the lower side of the cascade double-ring resonant cavity sensor is provided with a thermoelectric cooler. According to the invention, the sensor system is not influenced by external temperature through temperature control; according to the thermal tuning reduction method based on temperature control, the requirement for the bandwidth of a light source is lowered during wavelength detection, and the detection range of the sensor is enlarged during intensity detection; during structural design, cascade double-ring resonant cavity sensors with differ
