Method and device for controlling transmitter

A device for controlling a transmitter, comprising:

• an awaking module configured to awake and initiate the transmitter by a trigger signal generated by a timer;
• an input control parameter updating module configured to detect whether the transmitter receives an input control parameter from outside of the transmitter, and if yes, update an input control parameter stored in the transmitter by using the received input control parameter;
• an input control parameter reading module configured to read the input control parameter currently stored in the transmitter;
• a sensor signal acquiring module configured to perform operations based on the read input control parameter so as to control the transmitter to select one sensor signal from a plurality of sensor signals, amplify the selected sensor signal with a gain within a first gain range, and output the amplified sensor signal;
• and
• a sleeping module configured, after determining that the transmitter has accomplished a task specified by the read input control parameter, to reset the timer, and make the transmitter enter into a sleeping state until the timer generates the trigger signal.
