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
Spreadsheet Helper
Included with the Temperature Logger
Transferring Temperature Data into Notepad
• Temperature readings are not useful in the Terminal program
• Copy into Notepad using the Copy Input Buffer option
Editing Temperature Data
You get: 144,145,146,148
Edit to make it: 144145146148
