Abstract: The present invention relates to a method for receiving a pulsed signal emitted by an emitter (2,20) in an optoelectronic sensor (1), the sensor including at least an emitter (2,20) for emitting electromagnetic radiation and a receiver (3, 30) for receiving electromagnetic radiation and wherein the electromagnetic radiation received is converted into an electric signal, said method including the steps of: o arranging said emitter to emit a pulsed electromagnetic radiation; o before the emission of a pulse, receiving an electromagnetic radiation received through said receiver (3, 30) by generating a noise signal (sr,S1,S2); o comparing an amplitude of said received noise signal (sr,S1) with a first threshold (Vthreshold); and o emitting said pulse if the amplitude of said received noise signal is below said first threshold, and not emitting said pulse otherwise. The invention also relates to an optoelectronic sensor.
