Abstract
A sleep monitoring system () for monitoring the sleep of a pair of subject comprises a pair of CO2 sensors (') for mounting in different sleeping regions within a space () and a processor () communicatively coupled to the pair of CO2 sensors. The processor is adapted to, for each CO2 sensor in a particular sleeping region, monitor () a CO2 concentration from sensor data produced by the CO2 sensor in said particular sleeping region to detect a presence of a subject in said sleeping region; to register () the monitored CO2 concentration upon detecting () said presence; to determine () a degree of crosstalk between said CO2 sensors upon detecting said presence; and to derive () sleep pattern information for said subject from the registered CO2 concentration during said presence as a function of the determined degree of crosstalk, wherein the sleep pattern information comprises at least an indication that the subject is awake and an indication that the subject is asleep.
