An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) or probe or sond, is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analyzed. [1] It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Günter Bauman. [1]

The coefficient is defined as Lambda coefficient. If Lambda > 1 = lean mixture, excess of air. If Lambda < 1 = rich mixture, excess of gasoline. A lean mixture contains an excess of oxygen. The surplus oxygen will react with nitrogen to (oxides of nitrogen), if the temperature is high enough (around 1600 °C) for enough time to permit so.
Mono-Jetronic always had adaptive closed-loop lambda control, and due to the simple engine load sensing, it is heavily dependent on the lambda sensor for correct functioning. The ECU uses an Intel 8051 microcontroller , usually with 16 KB of programme memory and without advanced on-board diagnostics (OBD-II became a requirement in model-year 1996.)

Lambda (/ ˈ l æ m d ə / ⓘ; [1] uppercase Λ, lowercase λ; Greek: λάμ(β)δα, lám(b)da) is the eleventh letter of the Greek alphabet, representing the voiced alveolar lateral approximant IPA:. In the system of Greek numerals, lambda has a value of 30. Lambda is derived from the Phoenician Lamed. Lambda gave rise to the Latin L and the ...
Lambda is a high-speed (2,000 fps) big area (12 chips) readout systems developed at DESY. Lambda is available with high-Z sensor options, such as GaAs (Gallium-Arsenide) and CdTe (Cadmium-Telluride). Lambda is available with high-Z sensor options, such as GaAs (Gallium-Arsenide) and CdTe (Cadmium-Telluride).
There are several retinomorphic sensor designs which yield a similar response. The first designs employed a differential amplifier which compared the input signal from of a conventional sensor (e.g. a phototransistor) to a filtered version of the output, [6] resulting in a gradual decay if the input was constant. Since the 1980's these sensors ...
