Though a few works deal with similar kind of investigation, presentresearch delivers an accurate estimation of hemoglobin as compared to previous works. The principleof investigation is based on linear variation of both photonic band gap and absorbance’s with respect to different concentration of hemoglobin in human blood. Aside these variations, energy transmittedthrough honeycomb photonic crystal structure is also varied linearly with respect to same concentration.In this work, photonic band gap of honeycomb structure is found using plane wave expansion method,whereas absorbance of same structure is computed by employing Maxwell Curl equation. Finally, simulation result revealed that transmitted energy through two dimensional honeycomb photonic crystalstructure containing blood is nicely fitted with linear trend line (R2 = 1) which lead to an accurate investigation of hemoglobin in human blood. At last, this paper proposes an experimental set up to measurethe said concentrations with the help of an Arduino developmentboard(Uno)containingAtmega320microcontroller.Keywords:Honeycomb photonic crystal structurePhotonic band gapTransmitted energIntroductionPhotonics crystals are made, artificially created materials inwhich refractive index is periodically modulated in a scale comparable to the scale of the wavelength. Though the concept ofphotonic crystal has originated in the year 1857 by Lord Rayleigh,the research work in the field of photonic crystals is realized afteralmost 100 years, when Yablonovitch and John published twomilestone papers on photonic crystals in 1987 [1–3], since then,photonics have been progressin
