A circuit for converting the state of a sensor into a signal interpretable by an electronic circuit, including: a comparator of the voltage level of an input terminal with respect to a reference level, the sensor being intended to be connected between a terminal of application of a first power supply voltage and the input terminal; a current-limiting element between said input terminal and the ground; and a switching element in series with the current source and intended to be controlled by a pulse train.
