The invention relates to a position sensing device of an infrared source, a control device for fan blades and a temperature adjustment device. The position sensing device of the infrared source comprises a sensing unit, an amplifying unit and an angle calculating unit; the angle calculating unit is suitable for calculating the accurate position of the infrared source according to the output voltage of photoelectric sensors; when first voltage outputted by the amplifying unit is smaller than second voltage, the position angle beta of the infrared source is equal to (1-(V1-Vb) / (V2-Vb))*(-alpha / 2), wherein alpha is larger than 0 and is the angular degree of measurable angles of the sensing unit, Vb is the numerical value of the output voltage of the amplifying unit when the first photoelectric sensor and the second photoelectric sensor output no voltage, V1 is the numerical value of the first voltage, V2 is the numerical value of the second voltage; when the first voltage V1 is greater than the second voltage, the position angle beta of the source is equal to (1-(V2-Vb) / (V1-Vb))*(alpha / 2).
