Modern cars have sensors to monitor the vital organs of the car. These sensors play a vital role in ensuring the smooth operation of the car. Check what they are.
With the technological advances in the field of automobiles, almost every function of a car is based on electronic components. For a car to function effectively, it is necessary to know some important details about the car while it is in operation. With recent advances in technology, manufacturers also deploy an array of sensors to assist the driver. It’s going to be a fun journey to learn a few things about the sensors in our cars.
Important Sensors:
These sensors are essential for the safety and smooth functioning of the engine, which is the heart of the car.
Air Flow Sensor:

Located inside the combustion chamber, the air-flow sensor or air-mass sensor measures the density and volume of air entering the combustion chamber. The air-flow sensor ensures that the air-fuel mixture entering the combustion chamber is the correct amount to avoid engine stalling and excessive fuel consumption.

Part of the engine cooling system, the temperature sensor continuously monitors the temperature of the engine coolant. Its optimum functioning is very essential to keep the engine running safely and to avoid damage to the engine due to overheating.

Just as the air-flow sensor monitors the amount of air in the air-fuel mixture, the manifold absolute pressure sensor monitors the amount of the fuel component of the air-fuel mixture. The sensor does this by calculating the difference between the inlet manifold and the external pressure. ECU algorithms vary the injected amount of fuel based on changes in this pressure difference.
oxygen sensor:

Located near the exhaust manifold, the oxygen sensor measures the oxygen content of the exhaust gases. Based on the readings coming from this sensor, the ECU decides whether the engine is running on a lean or rich air-fuel mixture. Failure of this sensor can lead to increased fuel consumption, unstable idle speed and jerky engine operation.
Engine Speed Sensor:

Located on the crankshaft, the engine speed sensor provides the crankshaft rotation speed to the driver. This sensor also doubles as a crankshaft positioning sensor. Based on the data received from this sensor, the ECU controls the fuel injection timing and spark plug ignition timing.
Required sensors:
Although the car can function and run flawlessly without the functioning of these arrays of sensors, these sensors provide the driver with the necessary information to facilitate safe driving.

With the implementation of BS6 norms, speed sensors have become mandatory sensors. As the name suggests, the speed sensors monitor the speed of the individual wheels and ensure that the Anti-Lock Brake System or ABS is working properly. In addition, the speed sensor system also displays the vehicle’s running speed, making it essential for safe driving on the road.
NOX Sensor:

Located near the exhaust system, the NOx sensor, as its name suggests, monitors the emission values of hazardous NOx gases in the exhaust of the engine. Based on sensor data, the ECU dynamically calibrates the air-fuel mixture to keep these hazardous exhaust gases under control. With the increasing level of pollution and the implementation of BS6 standards, these sensors have become necessary to keep the level of air pollution under control.
Driver Assistance Sensor:
With the recent technological advancements, the latest cars come with multiple sensors to provide convenience to the driver. Parking sensors in the range of sensors, 360 . Are includedhey Camera system, adaptive cruise control sensor, LDR sensor for automatic headlamps, rain sensor for automatic wipers and much more. These sensors have recently become a common sight in manufactured cars as manufacturers start loading their car models with comfort features.
