Abrégé
The invention relates to a device for measuring an operating variable, to be fitted onto a tyre, comprising:
an electronic circuit distributed over a first face of an electronic board and comprising a sensor;
a protective housing at least partially covering the electronic circuit; and
at least one first antenna wire having one end galvanically connected to the electronic circuit and integrally extending so as to project laterally from the housing;
The invention relates to a device for measuring an operating variable, to be fitted onto a tyre, comprising:
