The invention discloses a calibration method and system for front-end sensing equipment, and belongs to the technical field of sensors. The method is used in a calibration system, the calibration system comprises a front-end sensing device and a control unit, the front-end sensing device comprises a sensor and a storage unit, and the control unit determines current performance parameters of the sensor according to measurement data of the sensor; the control unit reads factory information of the sensor from the storage unit, the factory information comprises an identifier and a reference performance parameter of the sensor, the factory information is written into the storage unit in advance, and the reference performance parameter is a performance parameter when the sensor does not generate a drift phenomenon; the control unit determines whether the sensor needs to be calibrated according to the current performance parameter and the reference performance parameter. The sensor can be identified according to the
