    en.wikipedia.org/wiki/Occupancy_sensor

    Occupancy sensor types include: PIR sensors, which work on heat difference detection, measuring infrared radiation.Inside the device is a pyroelectric sensor which can detect the sudden presence of objects (such as humans) who radiate a temperature different from the temperature of the background, such as the room temperature of a wall.

    en.wikipedia.org/wiki/Occupant-centric_building...

    Examples of implicit occupancy sensors includes CO 2 sensors and Wi-Fi-connected device count. [1] The selection of occupancy sensing devices depends on the size of the space being monitored, the budget for sensors, the desired accuracy, the goal of the sensor (detecting occupant presence or count), and security considerations.

    en.wikipedia.org/wiki/Smart_thermostat

    One issue with using a smart thermostat is the unreliability of the motion sensor. One of the main features of the smart thermostat is the ability to change the temperature when the sensor in the thermostat does not sense an occupant. The only sensor that is used though is the sensor in the thermostat.

    In theory, the Padres could still make a few minor moves, dump enough salary to get below the luxury tax, stand pat otherwise, roll into 2025 with the current group and hope for the best.

  9. Demand controlled ventilation - Wikipedia

    en.wikipedia.org/wiki/Demand_controlled_ventilation

    As the sensor reads the increasing amount of carbon dioxide levels in a space, the ventilation increases to dilute the levels. When the space is unoccupied, the sensor reads normal levels, and continues to supply the unoccupied airflow rate. This rate is determined by the building owner standards, along with the designer and ASHRAE Standard 62. ...
