Abstract: The invention relates to an electronic unit adapted to be positioned on the inner face of a tire tread and incorporating a pressure sensor (10) having a chamber (11) for measuring the pressure inside the tire. This electronic unit includes, in the first place, a housing (6) having a bottom wall (6a) and a side wall (6b) delimiting an open face opposite the bottom wall, the housing being adapted to rest on the tire via its bottom wall (6a) and to house the pressure sensor (10) so that the measuring chamber (11) of the latter opens opposite the open face of the housing (6). Moreover, the electronic unit includes a lid (7) for closing off the open face of the housing (6) pierced with at least one air-inlet opening (18) arranged so as to be offset relative to the measuring chamber (11) of the pressure sensor (10).
