Abstract: THE PRESENT INVENTION IS A SENSING SYSTEM AND METHOD WITH SUBSTANTIALLY REDUCED OR ZERO LIGHT EFFECT. THE ARRANGEMENT OF THE SYSTEM OF THE PRESENT INVENTION COMPRISES TWO SENSORS (10, 20); WHEREBY AT LEAST ONE A FIRST SENSOR (20) IS CONFIGURED TO DETECT LIGHT AND ONE A SECOND SENSOR (10) IS CONFIGURED FOR MEASURING SAMPLES; AN ANALOG READ-OUT CIRCUITRY CONNECTED TO AT LEAST ONETHE SECOND SENSOR (10), AT LEAST ONE ADAPTIVE GAIN CONTROL MEANS (40) CONNECTED TO THE LIGHT SECOND SENSOR (20) FOR OPTIMIZING THE OUTPUT FROM THE LIGHT SECOND SENSOR (20); AND A DIFFERENTIAL AMPLIFIER (50); WHEREIN THE ADAPTIVE GAIN CONTROL MEANS (40) IS CONFIGURED TO OPTIMIZE THE OUTPUT FROM BOTH SENSORS (10, 20) FOR LIGHT COMPENSATION, BY WAY OF EQUALIZING THE LIGHT COEFFICIENT FACTOR (?, ?) BY BOTH SENSORS (10, 20). FIG 3
