Eyes in space to spot bushfire danger zones

Scientists at the Australian National University (ANU) will lead the development of the first Australian satellite designed to predict where bushfires are likely to start and those that will be difficult to contain.

A fast light detector made of two-dimensional materials

Two research groups at ETH Zurich have joined forces to develop a novel light detector. It consists of two-dimensional layers of different materials that are coupled to a silicon optical waveguide. In the future, this approach ...

A sensor (also called detector) is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. For example, a mercury-in-glass thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated glass tube. A thermocouple converts temperature to an output voltage which can be read by a voltmeter. For accuracy, most sensors are calibrated against known standards.
