1. An atmospheric water harvesting system, comprising:
a heat pump having a hot side and a cold side;
a plurality of sorbent modules each containing one or more sorbents;
a desorption chamber encompassing said hot side of said heat pump,
wherein said desorption chamber configured to transfer heat from said hot side of said heat pump to at least one of said plurality of sorbent modules disposed in said desorption chamber to desorb water vapor from said one or more sorbents;
wherein at least one said plurality of said plurality of sorbent modules outside of said desorption chamber concurrently adsorbs water from surrounding air;
a condensation chamber encompassing, or positioned in close proximity to, said cold side of said heat pump, said condensation chamber configured to receive and condense water from said desorbed water vapor from said one or more sorbents;
a computer communicatively coupled to:
a desorption chamber temperature sensor located inside said desorption chamber; and
a desorption chamber humidity sensor located inside said desorption chamber.
