The NWS Web site features a handy on-line calculator for determining the heat index based on a combination of either temperature and relative humidity or temperature and dewpoint.
The sensor is composed of pyroelectric refrigerator and semiconductor detector, and controlled by a operator without model, In this way the air dew-point can be measured on line.
