Abstract: The present invention relates to a breath analyzer system for the detection of diabetes from exhaled breath and a process for the preparation thereof. In particular, the present invention provides a La doped Orthorhombic YFeO¬3 nanomaterial for sensing acetone, a DC voltage source and a microcontroller etcetera to convert the analog signal produced by the sensor into digital signal which is finally displayed via the LCD display. The instant invention senses acetone levels in the exhaled breath. More particularly, the present invention provides a process for fabrication the fabrication of La-doped Orthorhombic YFeO¬3 nanomaterial for sensing acetone level in breath, which is an indicator of diabetes. The YLF sensor exhibits excellent response and resolution to different low ppm acetone vapors (Rgas/Rair = 18 to 1 ppm, Rgas/Rair = 22 to ppm, Rgas/Rair = 28 to 5 ppm, and Rgas/Rair = 38 to 10 ppm acetone vapour), excellent resolution to healthy and diabetic breath (Rgas/Rair = 5 to healthy breath, Rgas/Rair = 21 to healthy breath + 1 ppm, Rgas/Rair = 25 to healthy breath + 2 ppm, and Rgas/Rair = 31 to healthy breath + 5 ppm, Rgas/Rair = 42 to healthy breath + 10 ppm acetone vapour), excellent selectivity of the sensor with respect to some other major gases/VOCs present in exhaled breath, such as, ethanol, H2S, NH3, and saturated moisture, excellent reproducibility of the sensor for at least 12 batches, excellent repeatability of the sensor for at least 10 cycles, and appreciable long-term stability of the sensor for at least 6 months. The YLF sensor exhibits highest response to trace acetone vapour (1 ppm-10 ppm) with respect to all other hitherto known compositions that make use of Y, La, Fe, and O.
