Our thermometer is very easy to use. The increment and decrement buttons mimic those of an alarm clock. When any of these buttons are held down for a long time (> 1 sec), the increment and decrement amounts change from a step size of .1° to .5°. Similarly, you can change temperature scales simply by repeatedly pressing a toggle button. The recorded maximum and minimum temperatures are also easily displayed by pressing the display max or display min push buttons.
Our digital thermometer is accurate in measuring temperatures to within .1°.
Fahrenheit (°F) is used as the base temperature scale, and all conversions are made from
this temperature scale. Formulas for computing the other scales are as follows:
|°F (base value)||Measured °C||Expected °C||Measured °K||Expected °K||Measured °R||Expected °R|
As mentioned earlier, the feature of being able to detect temperature boundaries set by the user makes our digital thermometer very extendable. Port pins B and B go active low when it is either too hot or too cold, respectively. Thus, this could act as the control signal to drive/trigger an external device such as a fan, heater, safety valve, etc...
