Hello!

I am Saakshi J. Shetty

I am here because I love to give presentations.

Today I am going to explain about SENSORS.

What are sensors???

Answer

  • A sensor is a device, module, machine, or subsystem whose purpose is to detect events or changes in its environment and send the information to other electronics, frequently a computer processor.
  • They are devices that convert physical properties into electrical signals.

Sensors In Vehicles

  • Air flow meter
  • Air–fuel ratio meter
  • Blind spot monitor
  • Crankshaft position sensor,A crank sensor is an electronic device used in an internal combustion engine to monitor the position or rotational speed of the crankshaft.

Sensors In Vehicles

  • Curb feeler, used to warn driver of curbs
  • Defect detector, used on railroads to detect axle and signal problems in passing trains
  • Engine coolant temperature sensor, or ECT sensor, used to measure the engine temperature
  • Hall effect sensor, used to time the speed of wheels and shafts, for example speedometer

Sensors In Vehicles

  • Knock sensor, used to detect detonation in internal combustion engines
  • MAP sensor, Manifold Absolute Pressure, used in regulating fuel metering.
  • Mass flow sensor, or mass airflow (MAF) sensor, used to tell the ECU the mass of air entering the engine
  • Oxygen sensor, used to monitor the amount of oxygen in the exhaust

Basic Examples

Let us see examples for sensors applications in automotives or vehicles.

Braking and Traction control

Antilock Braking System (ABS) Sensors connected to the wheel, measures the speed of the wheel and braking pressure and keeps sending them to ABS controlling When the driver applies the sudden brake, ABS system, with breaking pressure and speed data received from the sensors, releases the braking pressure to avoid skidding/locking of wheels. It is one of the critical safety aspects of vehicles.

Air Bags – Anti Cushion Restraint System (ACRS)

Crush sensors and accelerometers placed in the vehicle measures the force and sends it to During accidents on sensing the force exceeds the limit, ACRS will activate the Airbag and save the life of passengers.

Avoiding Collisions:

​

Proximity sensors in the front, back, and sides of the vehicle forewarn the driver of a possible Infrared, Video assistance, Ultrasonic technologies assist drivers while parking their vehicles.

Comfort and Convenience

Many sensors provide inputs and warnings to drivers on Vehicle Speed, Engine Speed, Fuel level, Tire pressure, Door/deck, light bulbs for driving comfort and convenience.
