Sensors Used In Cars
( Automobiles )
Introduction To Sensors
A sensor is a device that produces an output signal for the purpose of sensing of a physical phenomenon.
 Mass airflow sensor
 Engine Speed Sensor
 Oxygen Sensor
 Spark Knock Sensor
 Coolant Sensor
 Manifold Absolute Pressure (MAF) Sensor
 Fuel Temperature Sensor
 Voltage sensor
 Camshaft Position Sensor
 Throttle Position Sensor
Oxygen Sensor.
 Located in the exhaust stream, usually near the exhaust manifold and after the
catalytic converter, the oxygen sensor (or O2 sensor) monitors the content of
exhaust gases for the proportion of oxygen. The information is compared to the
oxygen content of ambient air and is used to detect whether the engine is
running a rich fuel ratio or a lean one. The engine computer uses this
information to determine fuel metering strategy and emission controls.
Mass Air Flow Sensor
 The MAF or Mass airflow sensor is one of the essential sensor used in
automobiles. This sensor is used in an engine of the car. This sensor can be
controlled by a computer and can calculate the air density in the engine. If
the working of this sensor halts, then the running of the vehicle will be
stopped. In addition, the usage of petroleum will be high. These sensors are
classified into two types namely vane meter & hot wire.
The Engine Speed Sensor
 The engine speed sensor in the automobile can be connected to the
crankshaft. The main purpose of this sensor is to monitor the crankshaft’s
rotating speed. So that fuel injection & the engine timing can be
controlled. There are different ways for the vehicle engine to stop
unexpectedly. So this sensor will stop that for car drivers.
