Abstract: Systems and methods for monitoring conditions in a room are disclosed. Sensors may be placed in a room that measure various environmental conditions of the room, such as temperature, CO2, ventilation, humidity, volatile organic compounds, sound, static, light, pressure and odor (e.g. H2S). Depending on the use of the room, a selected number of these measurements are signal conditioned to be able to be displayed in real time, or near real time, on a computer display monitor or other visual display in a three dimensional format or more called a sweet spot. At the same time the computer can display onto the visual display an optimum sweet spot that is calculated from an algorithm given the special features, contents, and the like that characterize the room. The deviation between 1he two sweet spots, i.e., actual and theoretical, may be calculated, and recommendations made on the visual display that will cause the actual sweet spot to coincide with the algorithm sweet spot.
