The project uses the microprocessor 8085 in coherence with an ADC(Analog to Digital converter) to display the temperature sensed by LM35 temperature sensor. The value of voltage corresponding to a particular temperature is converted to its digital value from 0 to 255 by the ADC. An interrupt is there forth send to 6.5 which is a level sensitive interrupt pin . The 8085 then uses the code to find out the corresponding value of temperature through the look up table. The seven segment corresponding codes are converted and are shown on the display .
