    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.

    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.

    Occupancy-aware control system: it is possible to sense the occupancy of the home using smart meters [11] and environmental sensors like CO 2 sensors, [12] which can be integrated into the building automation system to trigger automatic responses for energy efficiency and building comfort applications.

    en.wikipedia.org/wiki/Building_automation

    A temperature sensor in the zone provides feedback to the controller, so it can deliver heating or cooling as needed. If enabled, morning warmup (MWU) mode occurs prior to occupancy. During morning warmup the BAS tries to bring the building to setpoint just in time for occupancy. The BAS often factors in outdoor conditions and historical ...

    en.wikipedia.org/wiki/Fume_hood

    Comprehensive controls on a laboratory may necessitate the use of a mechanical sash controller module that will automatically close the sash and shut off ventilation in concert with motion sensors. [ 21 ] : 238 However, even without the use of sensors and mechanical sashes, providing reminders to fume hood users to shut the sash is more ...

    en.wikipedia.org/wiki/Mmwave_sensing

    Millimeter wave (mmWave) sensing is a non-contact system of using mmWave radar sensors to measure movement, acceleration, and angles as small as a fraction of a millimeter. [1] This system requires a mmWave radar sensor to transmit and receive pulses of millimeter electromagnetic wave energy, detecting targets and motion from the reflections it ...
