Description

This dataset includes the recordings of five replicates of an 8-sensor array. Each unit holds 8 MOX sensors and integrates custom-designed electronics for sensor operating temperature control and signal acquisition. The same experimental protocol was followed to measure the response of the 5 twin units. Each day, a different unit was tested, which included the presentation of 40 different gas conditions, presented in random order. In particular, the unit under test was exposed to 10 concentration levels of Ethanol, Methane, Ethylene, and Carbon Monoxide. The duration of each experiment was 600 s, and the conductivity of each sensor was acquired at 100Hz. Channel, sensor type (from Figaro), and mean voltage in the heater are as follows: 0: TGS2611 5.65 V 1: TGS2612 5.65 V 2: TGS2610 5.65 V 3: TGS2602 5.65 V 4: TGS2611 5.00 V 5: TGS2612 5.00 V 6: TGS2610 5.00 V 7: TGS2602 5.00 V Presented concentration levels are as follows (in ppm): Ethylene: 12.5, 25, 37.5, 50.0, 62.5, 75.0, 87.5, 100.0 , 112.5, 125.0 Ethanol: 12.5, 25.0, 37.5, 50.0, 62.5, 75.0, 87.5, 100.0 , 112.5, 125.0 Carbon Monoxide: 25.0, 50.0, 75.0, 100.0 , 125.0 ,150.0, 175.0, 200.0, 225.0 , 250.0 Methane: 25.0, 50.0, 75.0, 100.0 , 125.0 ,150.0, 175.0, 200.0, 225.0 , 250.0 Days in which each detection platform was tested.
