  4. Overview • To demonstrate an understanding of an ADC with relation to a MC • Fully implement a system that outputs temperature value on a BCD. Analog-Digital Converter and Temperature Sensor MC68HC912B32

  5. Scope • Successful use of the ADC within the MC will allows the needed conversion. • Reading the thermistor voltage value into the MC, converting it to Celsius using a predefined array. • Outputting the temperature onto 2 BCD displays

  6. Implementation • Temperature system code written in assembly • Control Case: • When temperature reaches a high and low limit, triggers LED green or red.

  7. Product Development There are many applications of our system such as: • Reading temperatures in various environments: atmosphere and land • Heating, Ventilating, Air Conditioning (HVAC) • Climate Control for small to large living/working areas (Offices, home, etc)
