Interpreting Temperature Logger Data

Changing Digitized Temperature Readings back into Temperatures

Analog Temperature Readings to Digital Values

• Analog: 0 to 5 volts• Digital: 0 to 255

D = (A/5) X 256

The LM335 Temperature Sensor

• Temperature: 0 to 500 kelvins• Output: 0 to 5 volts

Four Temperature Scales

• Kelvin• Celsius• Fahrenheit• Rankin

Fahrenheit and Celsius

• There are 1.8 Fahrenheit degrees in 1 Celsius degree

• -40O Fahrenheit = -40O Celsius

Converting a Digitized Temperature back into Temperature

Temperature (k) = R/256 X 500
