Embedded Microcontroller Based Non-destructive Seafood Inspection System

Introduction

In this chapter an embedded controller based sensing system for seafood inspection has been described. Interdigital sensors have been used for non-destructive and noninvasive inspection of system properties. There are many applications of interdigital sensors based systems – they are used in bio-medical field to monitor the change in impedance caused by the growth of immobilized bacteria; a micro-sensor based on interdigital electrodes is used to measure the water content in human body as the water content in the skin could be used as an index to confirm the health of human skin. The interdigital sensors can also be used for the estimation of fat content in pork meat and inspect the quality of saxophone reeds. The capacitive sensors can be interfaced with microcontrollers for effective signal processing. Detection of the presence of contaminated acid in seafood has been explained in this chapter.
