Oxygen sensor. 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. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Günter ...
Jan 6, 2023 · 02 sensors measure the amount of oxygen in the exhaust and report the level to your vehicle’s computer. There are O2 sensors before and after the catalytic converter. The upstream O2 sensor controls how much fuel is added to the air/fuel mixture. The downstream O2 sensor makes sure the catalytic converter is working.
Nov 11, 2024 · Published: Nov 11, 2024. An oxygen sensor (O2) is a vital part of the fuel and emission-control system. It measures the difference in oxygen in the air on the outside of and inside the exhaust. It reports its finding to the ECU to calculate the exact amount of fuel the injector should pulse into the cylinder to create combustion.

Jan 22, 2024 · Ultrasonic Oxygen Sensor. Ultrasonic oxygen sensors use sound speed to measure the amount of oxygen in a gas or liquid sample. In liquid, upstream and downstream sensors measure the velocity difference between high-frequency sound waves. The change in velocity is proportional to the amount of oxygen in the sample.
Pulse oximeters measure how much of the hemoglobin in blood is carrying oxygen (oxygen saturation). If you work in healthcare (or have been patient !) you are very likely to have come across pulse oximeters. You can find them in areas such as operating rooms, recovery, critical care, wards, and ambulances.
An oxygen sensor is an electronic device that measures the proportion of oxygen in the exhaust gasses exiting an engine. Located in the exhaust system, it provides real-time data to the vehicle’s Engine Control Unit (ECU), which uses this information to adjust the air-fuel mixture for optimal combustion. The primary goal is to maintain this ...

The sensor is part of the emissions control system and feeds data to the engine management computer. The goal of the sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. A gasoline engine burns gasoline in the presence of oxygen (see How Car Engines Work for complete details).
