Thermometer Designed using AT89C51 for Displaying Digital Records

Abstract

A digital thermometer is a simple low cost temperature measuring device which senses our body temperature and displays the output in 7 segment display. The normal temperature of human body is 78°F or 36.7°C (37°C). It is more accurate and efficient; since its cost is low it can be used in medical fields, to measure the body temperature of patients. In this fast developing world, we want quick and accurate result thus a digital thermometer is best over the analogy (mercury) thermometers. On completion of this project the temperature can be just with the simple touch on temperature sensor LM35.
