This is the circuit diagram of Celsius Scale Thermometer using 8051 Microcontroller. This circuit works on the principle of analog to digital conversion. Here, the temperature is sensed by a analog temperature sensor and this analog value is converted to a digital value using an ADC. A microcontroller then processes the digital signal to display the temperature reading in Celsius on the display screen.
