摘要： A sensor for a portable connected device. The sensor has a filter arranged to reduce a noise component on a sampled input signal. The is arranged to consider only input measurements that change systematically in a same direction, updating an output value when all the input samples in a predetermined time window are above or below a current output value and, repeating the current output value when the input samples in the time window are below and above the current output value.
