The integrated circuit sensor may come in a variety of interfaces — analogue or digital; for digital, these could be Serial Peripheral Interface, SMBus/I 2 C or 1-Wire.. In OpenBSD, many of the I 2 C temperature sensors from the below list have been supported and are accessible through the generalised hardware sensors framework [3] since OpenBSD 3.9 (2006), [4] [5]: §6.1 which has also ...
A sensor node, also known as a mote (chiefly in North America), is a node in a sensor network that is capable of performing some processing [1], gathering sensory information and communicating with other connected nodes in the network. A mote is a node but a node is not always a mote.
A wireless sensor node is a popular solution when it is difficult or impossible to run a mains supply to the sensor node. However, since the wireless sensor node is often placed in a hard-to-reach location, changing the battery regularly can be costly and inconvenient. An important aspect in the development of a wireless sensor node is ensuring ...
Sensors for arc welding are devices which – as a part of a fully mechanised welding equipment – are capable to acquire information about position and, if possible, about the geometry of the intended weld at the workpiece and to provide respective data in a suitable form for the control of the weld torch position and, if possible, for the arc welding process parameters.
Type I sensors have an electrolyte containing mobile ions of the chemical species in the gas phase that it is monitoring. The commercial product, YSZ oxygen sensor, [ 1 ] is an example of type I. Type II sensors do not have mobile ions of the chemical species to be sensed, but an ion related to the target gas can diffuse in the solid ...
Time-Temperature-Transformation diagram for two steels: one with 0.4% wt. C (red line) and one with 0.4% wt. C and 2% weight Mn (green line). P = pearlite, B = bainite and M = martensite. Isothermal transformation diagrams (also known as time-temperature-transformation ( TTT ) diagrams ) are plots of temperature versus time (usually on a ...
These sensors require a sufficiently small air gap and need to be particularly reliable. One special feature of rotary speed sensors that are used for wheel slide protection is their integrated monitoring functions. Two-wire sensors with a current output of 7 mA/14 mA are used to detect broken cables.
The first airport in Alta was built by the Wehrmacht during the German occupation of Norway. Alta was a central part of the German military activity during World War II, resulting in an airstrip being constructed at Elvebakken in 1943. [3] The airport was damaged beyond repair under Operation Nordlicht—the German withdrawal from Finnmark in 1944.
