The invention relates to a sensor for detecting resonance frequency and Q-value of a passive electronic tag. Interferences exist between the current transmission coils and the receiving coils and among tags, the transmission coils and the receiving coils. The sensor comprises two transmission coils and a receiving coil. The receiving coil is located between the two transmission coils, and the two transmission coils are closely arranged. Each transmission coil comprises a main transmission coil and an auxiliary transmission coil. The receiving coil comprises a main receiving coil and an auxiliary receiving coil. The sensor removes the mutual interferences between the transmission coils and the receiving coils, between the tags and the transmission coils and between the tags and the receiving coils, and solves the problems that the traditional sensor has the measurement errors of the resonance frequency because of the interferences among the parts so as not to test the Q-values of the electronic tags.
