Novel PCS Output Calibration Technique

Abstract

Many issues like large size, poor response time and accuracy which were plaguing the performance of the conventional Photo Catalytic Processes were overcome by PCS (Photo Catalytic Sensor). The continuing advancements in the field of sensor interface development are to calibrate and correct the inherent non-idealities present in transducers forced us to work in this area. The varieties of different parameters inside PCS subject to the transfer characteristics of PCS results because of Photo-catalytic oxidation of organic compounds has been done by Whig and Ahmad in 2015 and it is found that the major contributors to non-idealness are typically the nonlinear response to stimulus (gain), the temperature, and the offset dependence of either of these elements. Expectedly the calibration of the sensor has been done physically in the research facility available in laboratory before the genuine deployment in the system. This requires a great deal of manual calculation very high skilled manpower. To make this tedious procedure easy and to make PCS sensor more accurate, a novel sensor calibration with built-in calibration registers using FPGAs is proposed.
