The invention claimed is: 1. Sensor device for a household appliance, said device comprising: a body, detector means to measure at least one variable of a fluid and which comprise a conductivity sensor, a printed circuit that receives the variables measured by the detector means, and a cover; the body comprising: a housing where said printed circuit is housed, and an inlet conduit and an outlet conduit through which said fluid passes, the cover being arranged to close the housing of the body, and said printed circuit and said cover being disposed transversally to said inlet and outlet conduits between said inlet and outlet conduits, the conductivity sensor being connected to the body and connected to or next to said printed circuit. 2. Device according to claim 1, wherein the conductivity sensor comprises two electrodes that are disposed longitudinally and in parallel in one of the inlet or outlet conduits of the body, said electrodes being disposed longitudinal to the flow of the fluid and being connected to the printed circuit. 3. Device according to claim 2, wherein the electrodes are disposed in respective longitudinal grooves of the inlet conduit. 4. Device according to claim 3, wherein the longitudinal grooves comprise respective parallel stoppers, so that the electrodes extend longitudinally to the same length in the inlet conduit. 5. Device according to claim 2, wherein the body of said device comprises fixing means disposed in one of the inlet and outlet conduits, so that the electrodes are disposed in a certain position in relation to the flow of the fluid. 6. Device according to claim 1, wherein the conductivity sensor comprises two inductive conductors rolled up in one of the inlet or outlet conduits, said conductors being next to the printed circuit. 7. Device according to claim 6, wherein the conductors are rolled up in respective ring-shaped grooves of the inlet conduit, with said ring-shaped grooves being parallel and being separated by a certain distance. 8. Device according to claim 7, wherein the ring-shaped grooves are disposed on the outer surface of the inlet conduit, the body comprising insulation means disposed on said inlet conduit and concentric to said inlet conduit, so that said insulation means are disposed on said conductors, thereby insulating said conductors from the exterior. 9. Device according to claim 1, wherein the housing delimits an area around the outlet conduit of the body, the printed circuit being disposed on said area, and said printed circuit and the cover comprising respective cavities that are crossed by said outlet conduit as said printed circuit and said cover are disposed on said area. 10. Device according to claim 1, wherein the detector means comprise a turbidity sensor disposed on the printed circuit to measure the turbidity of the fluid that passes through the outlet conduit, said turbidity sensor comprising a light emitter and at least one light receiver, and the cover comprising guidance means to focus the light emitted by said light emitter and the light received by said light receiver. 11. Device according to claim 1, wherein the detector means comprise a turbidity sensor disposed on the printed circuit to measure the turbidity of the fluid that passes through the outlet conduit, said turbidity sensor comprising a light emitter and at least one light receiver, and the body comprising guidance means to focus the light emitted by said light emitter and the light received by said light receiver. 12. Device according to claim 1, that comprises a mixing conduit connected to the outlet conduit, said mixing conduit comprising a diameter substantially greater than the diameter of said outlet conduit. 13. Device according to claim 1, wherein the household appliance comprises at least one water pump and said device is integrated in said water pump, so that said water pump and said device form a single element.
