  2. Passive infrared sensor - Wikipedia

    en.wikipedia.org/wiki/Passive_infrared_sensor

    A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors . PIR sensors are commonly used in security alarms and automatic lighting applications.

  3. Occupancy sensor - Wikipedia

    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/InMoov

    InMoov is a humanoid robot, constructed out of 3D printable plastic body components, and controlled by Arduino microcontrollers. InMoov is a robot developed for artistic purposes by French sculptor Gaël Langevin [1] in September 2011. (The first blueprint files were published in January 2012 on Thingiverse. [2])
