A new widget has just been added to the emoncms dashboard which is useful for displaying the perceived temperature;
The Heatindex widget calculates this data from both temperature and humidity feeds as follows;
- Less than 50°F - as there is no calculations carried out below this temperature, the widget gives the option to display the ‘actual’ current temperature, or --°F.
- More than 50°F and less than 80°F - the calculation use the formula by R. Steadman.
- 80°F and over, the calculation formula by Rothfusz L is used.
There is an option to disable the calculations for more than 50°F and less than 80°F, so the widget only begins to calculate when the temperature is at least 80°F (true heatindex).
The same calculations apply in either Fahrenheit or Celsius.
Many thanks to Aymeric Thibaut for submitting.
