Abstract: An electronic device includes a light source, a light sensor, and a controller that senses an amount of a coarse ambient light by turning off the light source and performing sensing in a coarse mode by using the light sensor and senses an amount of a fine ambient light by performing sensing in a fine mode by using the light sensor. The controller senses an amount of a target light by turning on the light source and performing sensing by using the light sensor while the light source emits a light, and outputs information based on the amount of the coarse ambient light, the amount of the fine ambient light, and the amount of the target light.

Abstract: An electromagnetic (EM) sensor includes a front-end module, a memory, and a microcontroller unit. The front-end module generates an electromagnetic signal using externally introduced electromagnetic waves. The memory stores a first reference signal and a second reference signal generated from multiple probability models required to recognize the electromagnetic signal. The microcontroller unit compares the electromagnetic signal with the first reference signal and the second reference signal, to determine whether the electromagnetic signal is a valid signal.
