Brief Description about Automotive Sensor

Modern automotive has become intricate machinery compared to cars a couple of decades ago. A modern-day automotive onsists of numerous electrical components as mechanical parts are changed or assisted by electronic gadgets. One such vital electric element of a vehicle is the sensor. In this post, we throw light on different sorts of sensors in cars and their functions.

What is an Automotive Sensor?

An automotive sensor is an electronic device that monitors numerous facets of the car and sends information to the driver or ECU (Electronic Control System). In particular situations, the ECU instantly makes adjustments to the particular part based on the information received from the sensor. The below points cover more information concerning vehicle sensors.

Sensors can check numerous aspects of an automobile, such as its temperature level, coolant system, engine, oil pressure, exhaust degrees, vehicle speed, etc.

The human sense body organs (eyes, nose, mouth, tongue, and hands) are the best examples to recognize the working concept of sensing units. They send signals to the brain, which then makes a decision.

Similarly, automotive sensing units send signals to the ECU to make ideal adjustments or warn the driver.

The sensor is constantly monitoring the various aspects of the automotive from the moment the engine is fired up.

In a modern automobile, the sensors are everywhere, from the engine to the least essential electric element of the vehicle.

Functions of Automotive Sensor

The working concept of a sensing unit gives you a broad concept of the features of automotive sensors. Because there are many sensors in an automotive, tracking numerous systems and working of components, the features of auto sensors are broader than you envision.

Nevertheless, the key function of a sensor remains the same, although the aspect is monitoring. It sends info about the system it is tracking to the ECU. The data is passed on via predefined formulas, and based upon that, and the ECU makes adjustments. If the ECU cannot make the necessary changes, it sends a warning to the driver.

Automotive Sensors Types and Their Functions

Car sensors are smart sensors that can be used to control and process oil stress, temperature, emission level, coolant levels, and so on. Various kinds of sensors are used in vehicles, yet recognizing these sensors’ working is necessary. Regarding the function of these sensors, here we have listed some sensors used in vehicles and their functions.

  • Air-flow Sensor

It gauges the density and quantity of the air entering the burning chamber.

  • Engine Knock Sensor

It monitors engine knocking and ensures the air-fuel mixture is sparked appropriately.

  • Engine Speed Sensor

Keeps track of the spinning rate and setting of the crankshaft.

  • Camshaft Position Sensor

Monitors the placement and proper timing of the camshaft.

  • Manifold Absolute Pressure (MAP) Sensor

Monitors engine load by measuring the difference between the various and outside stress.

  • Throttle Position Sensor

Monitor the position of the throttle valve.

  • Voltage Sensor

Handles the idling speed of the vehicle.

  • Oxygen Sensor

It helps to measure the oxygen degree existing in the exhaust gases.

  • NOx Sensor

It determines the Oxides of Nitrogen (NOx) in the exhaust gases.

  • Temperature Sensor

Monitors the engine temperature level.

  • Fuel Temperature Level Sensor

Keeps an eye on the temperature of the gas getting into the engine.

  • Speed Sensor

Gauges the rate of the wheels.

  • Parking Sensor

It recognizes any obstacle in the vehicle’s front or back.

  • Rain Sensor

It identifies rainfall and sends a signal to ECU to activate the wipers.

Advantages and Disadvantages of Car Sensors

Below are the advantages of car sensors.

  • Automotive sensors make driving an easy task.
  • The sensor can quickly discover damaged elements in a vehicle.
  • Sensors ensure that the engine maintains correctly.
  • Sensors also enable automatic control of particular features such as windscreen wipers, headlights, etc.
  • The ECU can make exact adjustments with the information obtained from sensor.
  • Sensors can likewise pass on cautioning info to the motorist if there is any fault/malfunction with the car and truck’s components.

Here are some of the disadvantages of car sensor.

  • One major disadvantage of having numerous sensors on board is that they can fail gradually.
  • A damaged sensor can cause harm to crucial elements of the vehicle. Obtaining them fixed or replaced can be an expensive event.
