Low energy environmental sensor that receives inputs via movement thereof, and a method of operating a rocking environmental sensor

An environmental sensor for use with a heating, ventilating and air conditioning system, comprising:

• a processor configured to direct operation of said sensor based on a user input;
• and
• a rocking input system, including:
• a first component having a fulcrum point;
• and
• a second component including a first movement initiator area and a second movement initiator area configured to cause said second component to toggle with respect to said fulcrum point and complete a signaling path indicating said user input.

A method of operating an environmental sensor employable in a heating, ventilating and air conditioning (HVAC) system, comprising:

• receiving a user input via movement of said environmental sensor;
• generating a control signal in response to said user input;
• and
• performing a function in response to said control signal.
