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
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.

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)
