This document describes the design and implementation of a temperature meter. It includes sections on the circuit diagram, block diagram, coding logic, algorithm, and flowchart. The algorithm section outlines the 25+ step process for initializing the LCD, measuring temperature with an ADC, converting the output to Celsius, storing it in flash memory, displaying it, and comparing it to a threshold value. Applications are monitoring temperature in industrial systems and fire alarms. The document provides references and acknowledges contributions from the authors and guidance from professors.

Design and Implementation
Temperature Meter
Coding Logic
Algorithm 1) initialize lcd 2) start the adc to measure temp 3) read adc byte 4) convert adc byte into temperature and record into the flash 5) increase no of samples by one 6) display temp on lcd 7) compare the temperature with the threshold value 8) waiting time according to recording interval 9) start the conversion of ADC..conversion frequency is around 640KHz 10) convert adc digital output into temperature and store its 2 digit value into flash 11) increase number of samples by one 12) convert decimal to hexadecimal value 13) add one to hex value of no of samples 14) convert hex value to decimal number
15) display 2 digit temperature to LCD 16) compare temp value with threshold values 17) hex value of current temperature 18) hex value of threshold temperature 19) LED on if current temperature more than threshold value 20) LED off if current temperature more than threshold value 21) provide measuring interval delay 22) converts the adc 8 bit output to 2-digit temperature value in ASCII 23) convert the 4 digit decimal into 2 byte hex 24) Input in t3 t2 t1 t0 and output in hex1 hex0 25) provide threshold value range from 20 to 49 degree celcius for user 26) provide recording interval range from 01 to 99 secs for user 27) display a 16 byte in ASCII string on LCD 28) send the command to LCD 29) send ASCII data to LCD
