Abstract: Disclosed is an electronic device including an infrared sensor, a power supply part which supplies power to the infrared sensor. The electronic device controls the power supply part to supply a first power voltage signal with an on-duty ratio of less than 1 to the infrared sensor, and control, based on a trigger signal being received through the infrared sensor while the infrared sensor is operating based on the first power voltage signal, the power supply part to supply a second power voltage signal with an on-duty ratio of 1 to the infrared sensor.
