Sensor (source code)
= Sensor
A <sensor> converts a physical quantity into an observable signal. A <temperature> <sensor> might produce a voltage or resistance change that a measuring system converts into a <temperature> estimate. A useful model separates sensitivity, offset, noise, calibration and dynamic response: a large output change does not guarantee accuracy if the calibration drifts. <Sensors> also load the system they measure, for example by drawing heat or electrical current. The complete measurement chain includes the <sensor>, readout electronics and the model mapping the signal back to the intended quantity.
