Photoelectric sensors, also known as photo eyes, emit a beam of light that is used to detect the presence or absence of items and equipment or changes in surface conditions. When the emitted light is interrupted or reflected by the object, the change in light patterns is measured by a receiver and the target object or surface is recognized.

An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analysed.. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Dr. Günter Bauman. The original sensing element is made with a thimble-shaped zirconia ...

Passing combustible gas raises the temperature further which increases the resistance of the platinum coil in the catalysed bead, leading to an imbalance of the bridge. This output change is linear, for most gases, up to and beyond 100% LEL , response time is a few seconds to detect alarm levels (around 20% LEL), [1] at least 12% oxygen by volume is needed for the oxidation.

MOS technology is the basis for modern image sensors, including the charge-coupled device (CCD) and the CMOS active-pixel sensor (CMOS sensor), used in digital imaging and digital cameras. Willard Boyle and George E. Smith developed the CCD in 1969. While researching the MOS process, they realized that an electric charge was the analogy of the magnetic bubble and that it could be stored on …
