Temperature and Relative Humidity

Enter temperature (in Fahrenheit) and relative humidity (as a percentage without the "%" sign), separated by a comma, with up to 12 lines. Temperature must be an integer between 0 and 120, and relative humidity must be an integer between 0 and 100 (e.g., 70, 20 for Temperature = 70°F and Relative Humidity = 20%). Duplicate pairs of temperature and relative humidity are not allowed.
