Abstract
This paper elucidates simple design method of a low cost digital thermometer based on PIC16F77A microcontroller and temperature sensor LM35. LM35 is an analog sensor which converts the surrounding temperature to a proportional analog voltage. The sensor's output is connected to one of the ADC (Analog to Digital Converter) channel inputs of the microcontroller to originate the equivalent temperature value in digital format. Within a short duration 10 digital values of temperature are stored and computed to have maximum, minimum and average temperature among these. Then, the computed formats of temperature are displayed in a 16x2 character LCD in °C scale correspondingly. This design process is more convenient than others as it is more economical, efficient and simple.
