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

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

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

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)
