Using temperature and humidity sensors to evaluate the current conditions
of its operating environment, the water condenser calculates the optimal temperature at which water vapor will begin to condense from the ambient air (dew point).
This data is used in junction with thermocouple readings of the surface temperature of the condensing plate. This allows the microcontroller to determine if the air around the plate is too cool or too warm for optimal condensation.
Depending on these readings, a relay will cycle the compressor in the refrigeration cycle on or off to bring the surrounding air closer to the current optimal dew point. Water vapor will then condense on the plate and drip into the collection vessel below.
