Abstract: Disclosed is a device for attaching a sensor for a TPMS. The device for attaching a sensor for a TPMS includes: a module housing including a sensor module for a TPMS; a binding unit including a wire that is long enough to be wrapped on a wheel circumference portion of a vehicle and a rotation shaft installed in the module housing to wind or unwind the wire by a normal/reverse rotation; an engaging and fixing unit including an engaged groove and an engaged protrusion formed to generate an engaging and contacting force while being able to control an unwinding rotation corresponding to the rotation shaft of the binding unit; and a rotation unit disposed to rotate the rotation shaft of the binding unit and formed to release an engaging and contacting state of the engaging and fixing unit in connection with the rotating.

Abstract: A tire pressure monitoring system including a monitoring unit positioned in a tractor, a first repeater positioned in the tractor, a plurality of second repeaters positioned in a plurality of trailers connected to the tractor, and a plurality of sensors positioned at tires of the tractor or the trailers. A first RF transceiving unit transceives data with the first repeater by a low power RF transmitting unit to the plurality of second repeaters.
