A complete sensor consists of a motion detector, an electronic control unit, and a controllable switch/relay. The detector senses motion and determines whether there are occupants in the space. [9] It also has a timer that signals the electronic control unit after a set period of inactivity. The control unit uses this signal to activate the ...
Often instrumentation is not used by itself, but instead as the sensors of larger electrical systems. For example, a thermocouple might be used to help ensure a furnace's temperature remains constant. [80] For this reason, instrumentation engineering is often viewed as the counterpart of control.
Phase one mode is activated by a corresponding smoke sensor, heat sensor, or manual key switch in the building. Once an alarm has been activated, the elevator will automatically go into phase one. The elevator will wait an amount of time, then proceed to go into nudging mode to tell everyone the elevator is leaving the floor.
The Wii Remote, [a] colloquially known as the Wiimote, is the primary game controller for Nintendo's Wii home video game console.An essential capability of the Wii Remote is its motion sensing capability, which allows the user to interact with and manipulate items on screen via motion sensing, gesture recognition, and pointing using an accelerometer and optical sensor technology.
In electrical engineering, a stepping switch or stepping relay, also known as a uniselector, is an electromechanical device that switches an input signal path to one of several possible output paths, directed by a train of electrical pulses. The major use of stepping switches was in early automatic telephone exchanges to route telephone calls ...

The camera also has a 3-step ND filter switch allowing greater control of how much light can enter the camera for maintaining a shallow depth of field or giving a softer appearance to motion. For one hour video shooting in 4K the camera needs about 32 GB to accommodate a data transfer rate of 50 Mbit/s. The camera's MSRP in the US is US$2,000. [8]
The film was streamed in a global YouTube premiere in 2011 under a free licence through the website firstorbit.org. [76] In May 2013, commander Chris Hadfield shot a music video of David Bowie's "Space Oddity" on board the station, which was released on YouTube. [77] [78] It was the first music video filmed in space. [79]
