Intelligent Humidity-Compensated Thermostat

Built with an intelligent sensor, 68HC908QY4, and a couple of relays and switches, the thermostat periodically reads both the temperature and relative humidity of the inside air. Using a preprogrammed table, it compares these temperatures to user-defined preferences, and adjusts the heat or air conditioning accordingly.
