Abstract: The sunlight sensing apparatus includes a sensor portion which includes a first sensor sensing sunlight in a first direction and a second sensor sensing the sunlight in a second direction for altitude adjustment and includes a third sensor sensing the sunlight in a third direction and a fourth sensor sensing the sunlight in a fourth direction for horizontal rotation, in which the first sensor, the second sensor, the third sensor, and the fourth sensor are formed of the solar cells, a power supply portion which charges sensor power formed at the first sensor, the second sensor, the third sensor, and the fourth sensor through a photoelectric effect caused by the sunlight, and a control portion which performs a control operation for transmitting sensing signals. Here, the control portion is driven by the sensor power charged by the power supply portion.
