A piezoelectric accelerometer utilizes the piezoelectric effect of certain materials to measure dynamic changes in mechanical variables such as mechanical shock, vibration and acceleration.
Thermocouples are one of the most common sensors used for temperature measurement. They are made up of two different metals coupled together at one or more points.
Motion can be detected through various means such as infrared, sound, and vibration. Motion detectors are primarily used for detecting moving objects (especially people), and gathering data regarding position, acceleration, and velocity.
As the Earth is not a perfect sphere, its gravitational field strength fluctuates across its surface. Changes in topography, elevation, latitude, and subterranean density can affect the force of gravity.
A carbon paste electrode is a particular type of electrochemical sensor widely used in voltammetric experiments, made up of carbon paste.

A barometer is a device used to measure air pressure based on the weight of the air column.
A silicon bandgap temperature sensor is a type of thermometer or temperature detector commonly employed in electronic devices.
Oxidation reduction, or redox reactions, involves the transfer of an electron from a donor to an acceptor. The donor loses an electron to change from the reduced to oxidized form and the acceptor gains an electron to change from reduced to oxidized form.
