The invention relates to an interface circuit of a sensor, gearbox equipment and vehicle equipment, and belongs to the technical field of electronics and electrics. The interface circuit comprises a sampling module configured to provide a sensing voltage signal to an output end of the sampling module based on an electric signal from a sensing signal output end of a sensor, a voltage waveform of the sensing voltage signal having an upper envelope line and a lower envelope line; the detector module is configured to provide a reference voltage signal to the output end of the detector module based on the sensing voltage signal, the shape of the voltage waveform of the reference voltage signal is the same as that of at least one of the upper envelope line and the lower envelope line, and the voltage waveform of the reference voltage signal is lower than the upper envelope line and/or higher than the lower envelope line; and the comparator module is configured to provide a sensing result signal to the output end of the comparator module based on the sensing voltage signal and the reference voltage signal. According to the invention, acquisition of the output signal of the sensor can be stably and reliably realized on the premise of not depending on a special chip.
