1. A lens moving apparatus comprising:
a housing;
a bobbin disposed in the housing;
a magnet disposed on the housing;
a first coil disposed on the bobbin and configured to move the bobbin by an interaction with the magnet;
a sensing magnet disposed on the bobbin;
a first position sensor disposed on the housing so as to correspond to the sensing magnet;
a second coil disposed under the magnet;
a circuit board comprising a first terminal and a second terminal; and
a second position sensor including first and second sensors conductively connected to the circuit board,
wherein each of the first position sensor and the first and second sensors is a driver IC including a Hall sensor and a driver,
wherein the first terminal of the circuit board is provided with a clock signal and the second terminal of the circuit board is provided with a data signal,
wherein the driver of each of the first position sensor, the first sensor, and the second sensor transmits and receives the clock signal through the first terminal of the circuit board, and transmits and receives the data signal through the second terminal of the circuit board.
