  2. WEMO - Wikipedia

    en.wikipedia.org/wiki/WeMo

    The Wemo Motion Sensor can be placed anywhere, as long as it can access the same Wi-Fi network as the Wemo devices it is intended to control. It can then turn on and off any of the Wemo devices connected to the Wi‑Fi network as people pass by.

  3. 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.

    The former building - a light industrial warehouse from the 1920s - was once used as a practice space for one of Seattle's best known bands, Pearl Jam. [2] Most of the existing, two-story building was salvaged for reusable building materials and components, in particular, the brick and heavy timber. 93% of the materials reclaimed during demolition were recycled and 94% of construction waste ...

    en.wikipedia.org/wiki/Security_alarm

    The technology typically found in motion sensors to trigger an alarm includes infrared, ultrasonic, vibration and contact. Dual technology sensors combine two or more forms of detection in order to reduce false alarms as each method has its advantages and disadvantages. Traditionally motion sensors are an integral part of a home security system.
