Devices, systems, and methods are provided for monitoring air flow through a server using differential pressure measurements. The device includes an external pressure sensor, an internal pressure sensor, and a controller that receives the pressures from the external and internal pressure sensors. The external pressure sensor detects air pressure of the ambient air around a server enclosure, the internal pressure sensor detects air pressure through a server enclosure, and the controller calculates a pressure differential between the pressure from the external pressure sensor and the internal pressure sensor. The controller can then generate a signal based on the pressure differential, the signal optionally controlling a cooling fan, generating an interrupt for the server circuitry, or performing some other action.

Despite otherwise uncomfortable conditions in a surrounding environment, a customizable microenvironment can be created around a user to maintain a comfortable temperature and/or humidity level using a comfort unit. For example, the environment may be an office building where conditions are out of the comfortable range to save on energy or for other reasons, a factory/shop environment that is poorly conditioned, or an outdoor location with little to no conditioning. A sensing unit can monitor biometric and environmental data and can determine a comfort level of the user. The comfort unit can then dynamically respond to the determined comfort level and adjust the microenvironment to improve the user's comfort level. The comfort unit can follow the user as the user moves within the macro-environment, or can otherwise move within the macro-environment to achieve certain functions, such as recharging or spatial shifting of thermal load within the overall macro-environment.

A monitoring system is disclosed for a heating, ventilation, or air conditioning (HVAC) system of a residential or commercial building. The monitoring system includes an evaporator unit device including a first current sensor that measures current supplied to a circulator blower. The measured current from the first current sensor is used to diagnose a problem with the circulator blower. The monitoring system includes a first temperature sensor that measures refrigerant temperature between a condenser and an expansion valve. The monitoring system includes a second temperature sensor that measures refrigerant temperature between an evaporator and a compressor.

The controller is operable to determine a first temperature value related to a first temperature sensed by the first temperature sensor, determine a second temperature value related to a second temperature sensed by the second temperature sensor, and receive a command from the external controller. When the received command is a first command, the controller control current to the first heating element based on the first temperature value traversing a first set point, and controls current to the second heating element based on the second temperature value traversing a second set point. When the received command is a second command, the controller controls current only to the first heating element and not the second heating element, the control being based on the first temperature value.

The environment controller executes a neural network inference engine using first and second predictive models for respectively inferring temperature increase and decrease values based on environmental inputs. The environment controller calculates a temperature adjustment value based on the temperature increase and decrease values, and the temperature in the area is adjusted based on the temperature adjustment value. The environment controller receives a vote related to the temperature in the area transmitted by a user device. The environment controller determines, based on the received vote, values of a first and second reinforcement signals. The environment controller executes a neural network training engine to update the first and second predictive models based on the inputs, respectively the temperature increase and decrease values, and respectively the values of the first and second reinforcement signals.

The control operating unit connects to the environmental sensor, the electrical quantity sensor, and the resistance output unit. The resistance output unit additionally connects to a temperature controller to replace original resistive temperature sensor. The resistance output unit outputs a first resistance to the temperature controller so that a controlled device operates at a first power state. The resistance output unit also can output a second resistance to the temperature controller so that another controlled device operates at a second power state. When the control operating unit reads environmental information or time information, the resistance output unit outputs the first resistance or the second resistance after calculating by the control operating unit so that the controlled device operates at the first power state or the second power state.
