A sensor line, a measuring arrangement and a method detect a change in an ambient variable. The sensor line serves for detecting a change in an ambient variable, in particular the temperature. The sensor line has a first optical waveguide, a second optical waveguide and also a material that changes its transparency depending on the value of the ambient variable. The material is positioned between the first optical waveguide and the second optical waveguide in such a way that light from the first optical waveguide is able to be coupled into the second optical waveguide in an event of a change in the transparency.

A semiconductor device may include a semiconductor die having an active region. The semiconductor device may also include a thermocouple mesh proximate to the active region. The thermocouple mesh may include a first set of wires of a first material extending in a first direction, and a second set of wires of a second material. The second material may be different from the first material. In addition, the second set of wires may extend in a second direction different than the first direction of the first wires.

In an indoor environment on fire, automatic deployment of sensors disposed on, beneath or over the floor to look upward the ceiling to observe a body of smoke and flame risen near the ceiling allows important information regarding states and dynamics of the body of smoke and flame to be gathered at an early stage of fire (e.g. before arrival of firefighters). By distributing the sensors over the indoor environment, the states and dynamics of the body of smoke and flame are monitored holistically (i.e. as a whole) even at the early stage of fire. Such information is useful to predict development of the fire. In one implementation, a sensor is held in an infrastructure sensor holder mounted on the ceiling during normal time. Upon detecting occurrence of fire, the sensor drops from the holder to land on the floor and orients a sensing direction vertically upward to perform monitoring.
