In the blood glucose level measurement apparatus and method, the apparatus coupled to a patch with a microneedle formed in at least one area and configured to calculate a blood glucose level of a body fluid extracted from a user may calculate the blood glucose level by analyzing a reflected light beam reflected from the patch with a microneedle formed in a second area and correct the calculated blood glucose level of the user by analyzing data obtained by measuring a reflected light beam from a first area from which the body fluid is not extracted so as to measure a precise blood glucose level with an error being reduced in consideration of environmental factors influencing measurement.

Abstract: Provided are a fire detection apparatus and method for analyzing a spectral distribution of secondary light generated as primary light is scattered or transmitted through smoke particles to distinguish between fire smoke generated due to an actual fire and living smoke generated in daily life, thereby reducing non-fire alarms. When smoke enters the inside of the fire detection apparatus (100) due to a fire, secondary light (150) scattered or transmitted through smoke particles (140) is incident on the light receiver (120). Upon receiving the secondary light (150), the light receiver (120) outputs a spectrum (170) of the secondary light (150). The fire identification unit (160) receives and analyzes the spectrum (170) of the secondary light (150) and identifies whether the smoke particles (140) are particles of living smoke or particles of fire smoke.
