What are the methods for classifying sensors?

[VanBrady]

Sensor classification methods include: 1. Classification by application; 2. Classification by principle; 3. Classification by output signal; 4. Classification by measurement purpose. The characteristics of sensors include: 1. Miniaturization; 2. Digitalization; 3. Intelligence; 4. Multifunctionality; 5. Systematization; 6. Networking. The functions of sensors are: 1. Providing engine speed signals to the CPU; 2. Providing high-pressure diesel pressure signals in the common rail chamber to the ECU; 3. Measuring engine air flow and fuel flow and converting them into electrical signals; 4. Linking flow parameters with electrical signals through mechanical signals; 5. Detecting various gas concentrations; 6. Monitoring temperature in the powertrain and vehicle interior; 7. Measuring cylinder pressure, vibration, and combustion noise.
