  2. Motion detector - Wikipedia

    en.wikipedia.org/wiki/Motion_detector

    A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.

    A PIR motion detector used to control an outdoor, automatic light. A camera trap with PIR motion detector. An indoor light switch equipped with PIR-based occupancy sensor [1] A PIR-based motion detector is used to sense movement of people, animals, or other objects.

  4. Output signal switching device - Wikipedia

    en.wikipedia.org/wiki/Output_Signal_Switching_Device

    External Device Monitor (EDM). The device issuing the OSSD signals may have an EDM input. The EDM is used to verify that the controlled device (safety relay) did indeed open when the OSSD signals were dropped. The safety relay has normally closed contacts, which close when the relay is de-energized, thereby turning on the EDM input.

  6. Hall effect sensor - Wikipedia

    en.wikipedia.org/wiki/Hall_effect_sensor

    Hall effect devices used in motion sensing and motion limit switches can offer enhanced reliability in extreme environments. As there are no moving parts involved within the sensor or magnet, typical life expectancy is improved compared to traditional electromechanical switches.

  7. Zero speed switch - Wikipedia

    en.wikipedia.org/wiki/Zero_speed_switch

    Zero speed switches (ZSS) also known as Speed Actuating Sensing Switches [1] are used to detect whether a rotating shaft is turning (even at very slow speeds) [2] in various machines, conveyors, power plants, and in industries involving the production of cement, sugar, textiles, paper, etc. Zero speed switches mainly use electromechanical, electronic, or magnetic proximity technologies.

  8. Capacitive sensing - Wikipedia

    en.wikipedia.org/wiki/Capacitive_sensing

    self-capacitance, where the object (such as a finger) loads the sensor or increases the parasitic capacitance to ground. In both cases, the difference of a preceding absolute position from the present absolute position yields the relative motion of the object or finger during that time. The technologies are elaborated in the following section.
