Types of sensors in a car
Modern cars are equipped with a variety of sensors to monitor and optimize performance, safety, comfort, and efficiency. Here's a categorized list of common types of sensors in
1. Mass Air Flow (MAF) Sensor – Measures the amount of air entering the engine.
2. Manifold Absolute Pressure (MAP) Sensor – Monitors air pressure in the intake manifold.
3. Oxygen (O2) Sensor – Detects oxygen levels in the exhaust gases to manage fuel mixture.
4. Throttle Position Sensor (TPS) – Measures the position of the throttle valve.
5. Crankshaft Position Sensor – Tracks crankshaft rotation to control ignition timing.
6. Camshaft Position Sensor – Helps with valve timing and fuel injection.
7. Knock Sensor – Detects engine knocking or pinging.
8. Coolant Temperature Sensor (CTS) – Monitors engine coolant temperature.
9. Oil Pressure Sensor – Ensures the engine has proper oil pressure.
10. Fuel Pressure Sensor – Monitors the pressure in the fuel system.
🚗 Safety and Driver Assistance Sensors
1. ABS Wheel Speed Sensors – Used in anti-lock braking and traction control systems.
2. Parking Sensors – Detect objects around the car while parking.
3. Blind Spot Monitoring Sensors – Detect vehicles in the driver’s blind spots.
4. Collision/Proximity Sensors – Alert the driver of potential collisions.
5. Lane Departure Sensors – Monitor lane markings to prevent unintended lane changes.
6. Radar and Lidar Sensors – Used in adaptive cruise control and autonomous driving.
7. Airbag Crash Sensors (Impact Sensors) – Detect sudden deceleration to deploy airbags.
8. Tire Pressure Monitoring System (TPMS) Sensors – Monitor tire air pressure.
🌡️ Environmental and Comfort Sensors
1. Ambient Temperature Sensor – Measures outside air temperature.
2. Rain Sensor – Detects rain on the windshield for automatic wipers.
3. Sunlight/Light Sensor – Adjusts headlights and interior lighting automatically.
4. Cabin Temperature Sensor – Controls HVAC system for passenger comfort.
5. Humidity Sensor – Optimizes climate control to prevent window fogging.
⚡ Battery and Electrical System Sensors
1. Battery Voltage Sensor – Monitors battery charge status.
2. Current Sensor – Measures electrical current to ensure system health.
3. Alternator Sensor – Tracks alternator performance.
🛞 Transmission and Suspension Sensors
1. Transmission Fluid Temperature Sensor – Prevents overheating of transmission fluid.
2. Gear Position Sensor – Detects gear selected (P, R, N, D).
3. Suspension Height Sensor – Used in air suspension systems.
4. Yaw Rate Sensor – Measures rotation for stability control.
5. Steering Angle Sensor – Tracks the direction the steering wheel is pointing.
