The invention provides a compensation method and device suitable for a Hall sensor and a storage medium, and the method comprises the steps: obtaining a plurality of first Hall electric signals outputted by the Hall sensor in a first preset time period, and obtaining an average Hall electric signal based on the plurality of first Hall electric signals; obtaining a plurality of first compensation electric signals output by the Hall compensation piece in a second preset time period, and obtaining an average compensation electric signal based on the plurality of first compensation electric signals; determining a first average difference value between the average Hall electric signal and the average compensation electric signal, and obtaining a temperature change rate during compensation according to the first average difference value and a preset basic value; determining a first temperature interval of an environment where the Hall sensor is located according to the temperature change multiplying power, and determining a corresponding first temperature compensation strategy according to the first temperature interval; and compensating a Hall electric signal output by the Hall sensor at the current moment based on the first temperature compensation strategy to obtain a compensated second Hall electric signal.
Description
technical field [0001] The invention relates to the technical field of Hall sensors, in particular to a compensation method, device and storage medium suitable for Hall sensors. Background technique [0002] Hall sensors are widely used in various industrial and agricultural production practices. All scientific research and production processes must be converted into electrical signals that are easy to transmit and process. However, the sensitive elements of most sensors are made of metal or semiconductor materials. Its static characteristics are closely related to the ambient temperature. In actual work, due to the large change in the working environment temperature of the sensor and the large heat output caused by the temperature change, it will bring a large measurement error; at the same time, the temperature change also affects the size of the zero point and the sensitivity value, which in turn affects the The static characteristics of the sensor, so measures must be t...
