The sensing circuit 415 (e.g., the sensor module 1576) may sense a change in the current/voltage applied to the loop coil 411L of the power transmission circuit 411. The electronic device 10 may generate the amount of transmission power to be transmitted to the wireless power reception device 21 or 22 in response to the magnitude of the current/voltage applied to the loop coil 411L. That is, the electronic device 10 may change the amount of power to be transmitted depending on the change of the current/voltage applied to the loop coil 411L. For example, as the magnitude of the current/voltage applied to the loop coil 411L increases, the amount of power to be transmitted may increase, and as the magnitude of the current/voltage applied to the loop coil 411L decreases, the amount of power to be transmitted may decrease. In addition, the sensing circuit 415 may sense the temperature change of the electronic device 10. The sensing circuit 415 may generate power to be transmitted through the power transmission circuit 411, or may sense a temperature change caused by heat, which may be generated from the electronic device 10 during the transmission of the generated power to the wireless power reception device 21 or 22. For example, the sensing circuit 415 may measure at least one of the internal temperature and the external temperature of the electronic device 10. According to an embodiment, the sensing circuit 415 may include at least one of a current/voltage sensor and a temperature sensor.
