Sensing the Temperature

Stage 1
The Physical world

Temperature is measured in the analog world in Celsius

Stage 2
Sensing the temperature

A Temperature Sensor produces an output voltage relative to the temperature (Celsius).

Stage 3
Converting to a digital value

This stage involved the world of conversion (analog to digital) and is undertaken by an Analog-to-digital converter (ADC). It takes the voltage output from the sensor and converts it to a digital value

Stage 4
Calculating the temperature

With the digital value from the ADC the microcontroller can calculate the temperature.
