3. ABSTRACT
• Food freshness is a key factor for public safety.
Management and monitoring of food quality are
important in food storage and transition.
• awesome concept & technologies is applied .let
we see, at present we people not monitor
whether the raw food materials decay or not.
• PH-level variations in meats to the three
transitions in the spoilage processes. In this work,
we demonstrated and compared the pH profiles
of fish meats stored at two different
temperatures
4. INTRODUCTION
• Management and monitoring of food quality are important
in food storage and transition. Food safety issue is a vital
concern as shown in the Hazard and Critical Control Point .
• Conducting organic polymer sensors, on the contrary,
require a low operating temperature and usually are very
sensitive to moisture which may not be suitable for robust
applications. For piezoelectric crystal sensors, a good
quality of coating process is required during the fabrication
to maintain a consistent sensitivity .
• the enzyme sensors usually require complicated fabrication
processes such as the polymer treatment, temperature
control, and chemical compound mixing to achieve the
required sensing performance
5. WORK MODEL
• A prototype of a batteryless, wireless pH
sensing tag for continuous and real-time fish
meat quality monitoring has been
demonstrated.We proposed such a method as
a cost-effective solution to monitor food
quality in large quantity during storage and
delivery
•
6. EXISTING METHOD
• Many aspects of daily life and information used
for decision-making are already derived from
data collected in various sectors of the digital
economy. Everyday considerations like food,
health, the physical environment and human
interactions are monitored using information
collected, stored and analysed through digital
communications technologies. This section
examines sensing and monitoring developments
in use across various industry sectors
7. Literature Review 1
The effect of pH on the initiation of growth of cottage cheese spoilage bacteria
Outline:
The influence of pH on strains of Pseydomonas spp. and Enterobacter
agglomerans that cause spoilage of cottage cheese varieties during
storage at 7°C has been investigated. In a culture medium adjusted to the
required pH with HCl, 57 of 64 strains of Pseudomonas spp. grew at pH 4.8
when incubated at 7°C but a very low proportion of strains grew at pH 4.7
or pH 4.6 and none at pH 4.5. At 20°C some of the pseudomonads grew at
pH 4.4. Three out of nine strains of E. agglomerans grew at pH 3.8 when
incubated at 7°C and at pH 3.6 when incubated at 20°C. In cultures of E.
agglomerans at controlled pH and 20°C, after a lag phase the doubling
time at pH 4.1 was 2 h, and at pH 7.0 was 1.4 h.
8. Literature Review 2
Wireless implantable microsystems: high-density electronic interfaces to the
nervous system
Outline:
Describes the development of a high-density electronic interface to the
central nervous system. Silicon micromachined electrode arrays now permit
the long-term monitoring of neural activity in vivo as well as the insertion of
electronic signals into neural networks at the cellular level. Efforts to
understand and engineer the biology of the implant/tissue interface are also
underway. These electrode arrays are facilitating significant advances in our
understanding of the nervous system, and merged with on-chip circuitry,
signal processing, microfluidics, and wireless interfaces, they are forming the
basis for a family of neural prostheses for the possible treatment of disorders
such as blindness, deafness, paralysis, severe epilepsy, and Parkinson's
disease.
9. PROPSED METHOD
• Sensing and monitoring involves the collection
of data that ultimately feeds into private and
public information systems, which increasingly
form the basis of consumer services.
15. 8051 Standard
• Microcontroller manufacturers have been competing for a long time for
attracting choosy customers and every couple of days a new chip with a
higher operating frequency, more memory and upgraded A/D converters
appeared on the market
• However, most of them had the same or at least very similar architecture
known in the world of microcontrollers as “8051 compatible”. What is all
this about?
• The whole story has its beginnings in the far 80s when Intel launched the
first series of microcontrollers called the MCS 051. Even though these
microcontrollers had quite modest features in comparison to the new ones,
they conquered the world very soon and became a standard for what
nowadays is called the microcontroller
17. Liquid Crystal Displays (LCD)
An LCD display is specifically manufactured to be used with microcontrollers,
which means that it cannot be activated by standard IC circuits. It is used for
displaying different messages on a miniature liquid crystal display.
The model described here is for its low price and great capabilities most frequently
used in practice. It is based on the HD44780 microcontroller (Hitachi) and can
display messages in two lines with 16 characters each. It displays all the letters of
alphabet, Greek letters, punctuation marks, mathematical symbols etc. ‘
In addition, it is possible to display symbols made up by the user. Other useful
features include automatic message shift (left and right), cursor appearance, LED
backlight
