Abstract
A method and an apparatus for detecting a background noise of a sensor, relating to the technical field of electronics, are provided. The method for detecting a background noise of a sensor includes: receiving a sampling value output by the sensor and judging whether the sampling value falls within a background noise acceptable range; selecting the sampling value as a current background noise sampling value when the sampling value falls within the background noise acceptable range; and calculating a current background noise of the sensor according to a previous background noise and the current background noise sampling value of the sensor. Also provided is an apparatus for detecting a background noise of a sensor.
