【Abstract】 Water temperature is detected by a sensor, and then temperature signal is converted into electromagnetic waves which is transmited by the FM transmitter. The electromagnetic waves is received and converted into temperature signal by a FM receiver. So measuring water temperature in the distance can be achieved.更多还原
