A versatile detection circuit. A detection circuit optimized for low sensor voltages comprising a microprocessor (4), the microprocessor (4) comprising an integrated analog-to-digital converter (9) with an input pin, the integrated analog-to-digital converter (9) being configured to rely on a reference voltage of no more than 2 V, said detection circuit also comprising a transformation circuit for transforming a sensor (2, 102, 202, 302, 402) signal, said transformation circuit being connected to the input pin of the integrated analog-to-digital converter (9), characterised in that the transformation circuit may comprise an impedance converter (13) and with the exception of an impedance converter (13) relies only on passive electric elements (111, 112, 408, 409, 411, 412, 705, 706). |
