The embodiment of the invention discloses a sensor control method comprising controlling a sensor on a circuit via each sensor on a traversal sensor concentrator, acquiring an equipment sign of a traversal sensor and state information of the equipment sign, and caching the same, intercepting a sensor dormancy order, acquiring a target equipment sign corresponding to the intercepted sensor dormancy order, seeking state information corresponding to the target equipment sign in the cache memory and setting the sought state information to dormancy, acquiring a sensor corresponding to the target equipment sign, and closing the sensor corresponding to the target equipment sign via a preset interface function. The invention further discloses a sensor control device. By the use of the sensor control device, terminal power consumption during dormancy of the sensor can be reduced and user experience can be improved.
