Abstract
An air velocity sensing system not requiring external power supply is applied to an air duct system, comprising: (1) a sensor module disposed in the air duct for measuring the air velocity therein and for saving the measured air velocity value; and (2) a control module for wirelessly transmitting a signal to the sensor module, which sends the measured air velocity value back to the control module after receiving the signal from the control module, so as to have the air velocity value displayed on control module. The present invention also provides an air velocity sensing method not requiring external power supply.
