Abstract

Temperature measurement in today’s industrial environment encompasses a wide variety of needs and applications. To meet this wide array of needs the process controls industry has developed a large number of sensors and devices to handle this demand. Temperature is a very critical and widely measured variable for most mechanical engineers. To medical practitioner’s temperature is a fundamental quantity that must be measured in order to attain healthy life in the world of medicine but to the world of engineering temperature is either conserved for the purpose of effective work or release not to damage the job. The need to measure and quantify the temperature of something started around 150 A.D. when Galen determined the ‘complexion’ of someone based on four observable quantities. The actual science of ‘thermometry’ did not evolve until the growth of the sciences in the 1500’s the first actual thermometer was an air-thermo scope described in Natural Magic (1558, 1589), which all lead to the development of thermometer. The first calibrated thermometer was the liquid in glass thermometer which was later divided in mercury in glass thermometer and alcohol in glass thermometer. During the invention of this thermometer some facts were not in place which lead to their disadvantages and with the aid of technology advancement digital thermometer came into existence. Digital thermometer brings together the likes of microcontroller to be interfaced with Lm35 temperature sensor all together working with an embedded C programming language. In advancement in technology, digital thermometer can be added to home automation utilizes, IOT service for medical records, industrial jobs and many more.
