A method for detecting an analyte in a fluid sensed by a group of sensors comprising a first sensor and a second sensor having different sensing procedures or different structures, wherein said first sensor and said second sensor are both sensors for which a change of the value of one physical parameter implies changes of a value of a another physical parameter representative of at least the concentration of an analyte, said method comprising: - obtaining a first set of values from the first sensor of at least a first and a second physical parameters, said first parameter varying monotonically within a range of values, each value of the second parameter being associated with at least a value of the first parameter, said second parameter being representative of at least a concentration of the analyte and comprising at least a first local extremum for a first value of the first parameter; - obtaining a second set of values from the second sensor of a third and a fourth parameter, said third parameter varying monotically within a range of values, each value of the fourth parameter being associated with at least a value of the third parameter, said fourth parameter being representative of at least a concentration of the analyte and comprising at least a second local extremum for a second value of the third parameter; - accessing at least a database of reference values of the first parameter from a sensor of the same type as the first sensor, and reference values of the third parameter from a sensor of the same type as the second sensor; - searching said at least a database for a reference value of the first parameter in relation to an extremum of the second parameter, and a reference value of the third parameter in relation to an extremum of the fourth parameter closest to the first value of the first parameter, respectively the second value of the third parameter; attributing a score of relevance to said analyte, according to the closeness of the first value of the first parameter and the reference value of the first parameter for said analyte, the closeness of the second value of the third parameter and the reference value of the third parameter for said analyte, and a ratio between a first ratio between the first local extremum and the second local extremum, and a second ratio representative of the differences of sensitivities of the two sensors, anddisplaying said score, wherein the reference value of the first parameter is the value of the first parameter present in the at least a database which is the closest to the first value of the first parameter, and the reference value of the third parameter is the reference value of the third parameter present in the at least a database which is the closest to the second value of the third parameter. - obtaining a first set of values from the first sensor of at least a first and a second physical parameters, said first parameter varying monotonically within a range of values, each value of the second parameter being associated with at least a value of the first parameter, said second parameter being representative of at least a concentration of the analyte and comprising at least a first local extremum for a first value of the first parameter; - obtaining a second set of values from the second sensor of a third and a fourth parameter, said third parameter varying monotically within a range of values, each value of the fourth parameter being associated with at least a value of the third parameter, said fourth parameter being representative of at least a concentration of the analyte and comprising at least a second local extremum for a second value of the third parameter; - accessing at least a database of reference values of the first parameter from a sensor of the same type as the first sensor, and reference values of the third parameter from a sensor of the same type as the second sensor; - searching said at least a database for a reference value of the first parameter in relation to an extremum of the second parameter, and a reference value of the third parameter in relation to an extremum of the fourth parameter closest to the first value of the first parameter, respectively the second value of the third parameter;
