This mean only my sensor and focal length is important for the FOV?
Yes, for the field of view only the sensor size and focal length matter. But you seem to have messed up your calculations.
The camera you linked in your first post have a 1/1.8 sensor, this means that the sensor diagonal is 1/1.84 inch. This gives a sensor size of 7.176 mm horizontal and 5.319 mm vertical (assuming you use the cameras in landscape mode).
If you use a lens with focal length of 1.5 mm you will get the following field of view:
HFOV = 2*ARCTAN(SH /(2*FL)) = 2 * ARCTAN ( 0.007176 / (2 * 0.0015)) = 2,35 radians = 135 degrees
VFOV = 2*ARCTAN(SV /(2*FL)) = 2 * ARCTAN ( 0.005319 / (2 * 0.0015)) = 2,11 radians = 121 degrees
